bawomolo:
we technically are supposed to solve them using calculus

O-boy, I don almost forget all the methods for Calculus except Taylor's theorem cos now I mostly deal with P.D.E's and na computer we dey use solve everything so I got to use Ibo man sense solve the questions.

^^^Yeah . . . . . . and which African leader did not spoil their economy?

We are asking for the best out of a bad bunch. Even the leaders who followed all the IMF and World bank steps still got f*cked over.

bawomolo:
find the area of a circle if x^2 + y^2=4

If this is a circle with centre (0,0),

then the radius is 2, just apply pie x r²

or 4 x pie

= 88/7

= 12.5714m²

bawomolo:
ah well u guys want a tough question.

find the maximum value of cosine(x^2-y^2) if x^2+y^2=1

Max cosine = Cosine of zero = 1.

Using that logic and knowing that x² or y² cannot be negative, I would say that both x² and y² are definitely less than 1.

So . . . . . . .

If x² = 0.5 and y² = 0.5, then x² - y² = 0 and cosine(0) = 1

Tentatively, I will suggest that the max value of cosine(x²-y²) = 1

I could be wrong. It sounds too obvious to be true.

bawomolo:
this would be much easier if we knew the flow rate or relevant equations

OK:

The relevant equation is the continuity equation:

rate of mass accumulation = rate of mass in - rate of mass out

Rate of mass in is zero

Rate of mass out = density x velocity through taphole x Area of taphole


Therefore, this is the equation you start with:

the time differential of mass = 0 - (density x velocity through taphole x Area of taphole)

remember: mass = density x volume

[center]Belletti Faces Chelsea Chop - Report[/center]
Chelsea defender Juliano Belletti could get the axe this summer as part of Avram Grant’s proposed clearout…
The Brazilian full-back, signed by Jose Mourinho last summer for ₤4 million from Barcelona, has failed to impress Grant since the Israeli took charge in September.

The 31-year-old has fallen well down the pecking at Stamford Bridge following a poor display in Chelsea’s Carling Cup final defeat to Tottenham, with Paulo Ferreira regaining his place at right-back.

Even midfielder Michael Essien has been preferred to Belletti in recent times, and could well start on the right side of defence against Manchester United in the Champions League final next Wednesday.

The former Villarreal man has a year remaining on his ₤35,000-per-week contract, and could well be used as a makeweight if Chelsea pursue their interest in bringing Valencia striker David Villa to London.

^^^OK, you like tough Calculus questions? Oya solve this one:

An open-ended rectangular water tank of diameter 3.1m contains water which flows out through a tap at the bottom. The taphole has a diameter of 0.075m. The height of the water is 3.5m at time t₀ and take the density of the water as 7100Kgm^-3. If the velocity at the taphole is V = sqrt(2gh) where h(t) is the instantaneous height and gravity is 9.81ms^-2, find the time taken to empty the container.

Hint: You need to integrate dh/dt

Julius Nyerere was the best.

^^^Yeah right! So if a black person says she is "killing em dead", then you automatically judge her as referring to white people? That does not follow your ususal logic because if it was the other way around, you would defend the white person. You give the policemen the benefit of doubt, but not Alicia? WOW!

For your info, Alicia Keys grew up in a white home, with a white mother who follows her everywhere, even on tour.

As for being taken out of context, don't the media do that to celebrities all the time?

MyTempID, I will come to your question later. It requires a lot of solving.

Anyway, this question is specifically for Pmann or anyone who wishes to take on the challenge. It involves Calculus:

An open-ended rectangular water tank of diameter 3.1m contains water which flows out through a tap at the bottom. The taphole has a diameter of 0.075m. The height of the water is 3.5m at time t₀ and take the density of the water as 7100Kgm^-3. If the velocity at the taphole is V = sqrt(2gh) where h(t) is the instantaneous height and gravity is 9.81ms^-2, find the time taken to empty the container.

Hint: You need to integrate dh/dt

^^^Ehe - I don catch you! I KNEW it was Alicia Keys you were referring to. I just wanted to get confirmation. Firstly, this whole issue was completely blown out of context. Secondly, it has been strenously denied. Thirdly, come on man, we are talking about Alicia Keys. My lovely Alicia Keys!    . Only a far-right mind would associate someone like Alicia Keys with this comment. I would provide links but I can't be bothered to.

As she said:

“The point that I was trying to make was that the term was oversloganized by some of the media causing reactions that were not always positive. Many of the `gangsta rap’ lyrics articulate the problems of the artists’ experiences and I think all of us, including our leaders, could be doing more to address these problems including drugs, gang violence, crime, and other related social issues.”

As for the AK-47 remark, Keys said Tuesday that AK-47 is a nickname given to her by friends “as an acronym for Alicia Keys and a metaphor for wowing people with my music and performances, `killing ‘em dead’ on stage. The reference was in no way meant to have a literal, political or negative connotation.”

What angers me most in politics?

Kobojunkie!

Kobojunkie:
Just some weeks ago, a hollywood artist claimed that the white government invented HipHop music to cause black people to shoot each other. That there shows how much intelligence she feels africans and african americans have. By the statement she made, she already made up her mind that black people are idiots and so easy puppets for any person with an idea or an agenda. I wonder when black people will start taking offence to such.

Please give us the link - which Hollywood actress? Or did you get this story from Fox News?

Well, this is what the BBC website is reporting. As we all know The Express is a gutter tabloid and The Mirror have respectable football writers especially Oliver Holt. So you choose who you believe:


Real Madrid are steeling themselves for a major attempt by Chelsea to sign their international defender Sergio Ramos for £50m. (Daily Express)

Although the Blues are apparently only going to offer £20m for Ramos. (Daily Mirror)


I don't think Madrid will be 'steeling' themselves for a £50m bid. They will be doing cartwheels. Stupid journalists!

Diego Capel is a left winger for Sevilla. You can youtube him.

Fashi this Ramos talk. No need to dey make person vex for nothing. We go believe am when we carry eye see am.

Spuds are in for Capel. His buy-out clause is 11.5m. Should we go for him?

Uche2nna:
I believe You must be talking about Blessing Kaku

Yeah, him.

I will believe it when I see it. If it happens, I will take some boys and go and riot outside the Bridge. Infact, I will switch to supporting Fulham.

^^^Na lie. If there was any substance to it, the major news agencies would have picked it up. LBc must have made up that figure - its probably 55m dollars and they converted it to pounds by mistake. As you know, Ramos is fighting Madrid for a new contract. I believe this rumour was leaked by his people to ensure that Real Madrid give him top dollar. Remember that Milan are also linked with him. Plus he is now a right back, not a centre-back - infact, he is probably the best right-back in the World. I would pay 20-25m for him, but definitely not 55m. Somebody dey smoke Igbo.

Nateevs, I can't find your story on any website. Must be a silly rumour. If Chelsea pay 55m for Ramos, I will stop supporting.

nateevs:
Chelsea offer £55m for Sergio Ramos. . . .

Is it the radio and TV or are my ears low on battery . . . . I need to change source of power because this can't be true in ten life times. . . £55m Is someone f**king crazy at the bridge? What in this flipping world does he do? he must be a striker, a goal keeper and a coach at the same time. . .


Please someone tell me it was me and not the news. . . because I don't know whether to laugh or cry. .

Source please . . . . . . . . I still dey work.

You should never ever pay more than 30m for a player. You know what AC Milan president Galliani said: Footballers are like cars, they change condition from year to year.

^^^^ I never thought he was good enough for us anyway.

ow11:
This saga reminds me of Ben Akwuegbu's spell with the super eagles. The guy couldn't even tear the austrian teams nets with goals yet found his way into the eagles and only managed a goal or two before his forced retirement.

Hehehe . . . . Akwuegbu. I remember I went to one Super Eagles game @ Loftus Road. I think it was against either Paraguay or Jamaica, I can't remember.  Akwuegbu was playing. The guy was so poor, me and my friends started chanting "Akwuegbu off, Akwuegbu off!". Soon enough, our whole section of the ground started chanting the same thing and they had to take him off quick quick.

Even that Okocha's friend was playing, the one that ended up at Bolton and didn't play a single game. I don forget in name. I think it was Ikechukwu Kalu. That guy was wastepipe.

No, but seriously, there must be at least 20 guys ahead of Odejayi in the pecking order. From Martins to Yak, Utaka, Uche, Odemwingie etc, even Anichebe. Striker is not our problem at all. We need wingers.

You also won't find this story on any of the major websites. I am sure Somze is interested in this one:

[center]Ben Arfa To Marseille?[/center]
Young French international Hatem Ben Arfa's future at Olympique Lyon grows evermore uncertain as president Jean-Michel Aulas hinted in newspaper La Provence that OL would be willing to listen to offers for the player.

Having struggled to break into the Lyon starting eleven on a regular basis in recent weeks, twenty-one year-old Ben Arfa was said to be “unhappy” by Aulas in the press last week, although made no statement himself.

This very public declaration struck observers as a message to interested parties to bid for the young French international; however Aulas has taken matters a step further today by strongly hinting that the wing-forward could be used as a makeweight in a deal for Marseille's Samir Nasri.

There is no secret of Lyon's admiration of the creative midfield player while Marseille, along with Arsenal, have been made favourites to sign Ben Arfa.

Comments made in La Provence today are certainly designed to act as a catalyst for Marseille to move.

Lyon's President is quoted as saying,  "If Marseille contacted us for Hatem, would we be ready to yield to him? I answer: why not? Nothing prevents us from considering such an offer.

"Marseille are a large club where Hatem could be just as easily affirmed as abroad. Precisely, the idea to see this young talent continuing to play in France would allure me. It would be a good thing for Ligue 1."

^^^^^I think Soccernet is the only one that is competing with goal.com to be honest. For editorials, I would say timesonline is the best, followed by Soccernet - but when it comes to real insight about every club in Europe and every transfer that may be taking place, goal.com is the best. For example, everyday, BBC give you the transfer gossip that is going on - but goal.com provide a background to the transfer, who was seen with who from which club at which restaurant etc.  The reason is because Goal.com has multi-language services such as Italian, Portuguese, Spanish etc. If an Italian journalist sees an interesting story breaking in Italy, it is quickly transferred into English and we all find out. Other sites are not multi-language so they don't have this advantage except Soccernet.

For example, check out this story which is just breaking on goal.com - you wont find it on other sites . . . . .

[center]Ronaldinho Close To Retirement?[/center]
News daily Adn claims that Ronaldinho's fitness condition is worse than thought, stating that the Barcelona star may never be fit for top-level competition again,

The Brazilian ace is reported to have undergone a medical last week at the Delfos clinic in Barcelona to check on his physical condition at a time in which he is trying to find a new club to kick-start his career.

His medical, which was done in secrecy, allegedly determined that Ronaldinho's "ominous" condition does not allow him to continue playing at a high level.

Meanwhile, Barcelona and coach Frank Rijkaard have apparently stated that they did not know about the Brazilian's medical exam.

The Spanish daily claims that, while the reason for Ronaldinho's medical is unknown, it may have to do with AC Milan's interest in the 28-year-old.

The rossoneri's desire for the Brazilian may now be non-existent after chairman Silvio Berlusconi said that the Barcelona footballer was no longer a great target.

Ronaldinho, who has been out of action for almost two months, is currently undergoing a recovery program, but his taking part in the club's closing fixtures seems to be out of the question.

The Diarra I mentioned was Mahamadou Diarra, not Lassana oh!

^^^No, that is not the point. Reyes was a flop. Flamini was not. As for Edu, injuries have ended that debate. Even in your run to the CL final two years ago, Flamini played a brilliant role at left back. Plus, I have always been impressed with his workrate and technical proficiency as far back as 3 years ago. Flamini's performances should have guaranteed him a new contract as far back as two years ago, even before the stellar season he's just had. Look at Man Utd and Chelsea - John O'Shea, Paulo Ferreira and players of that nature always get their contract renewed. How much more a player like Flamini? The article is asking why Wenger waited till this season to even begin discussions over a new contract. That would never happen at Chelsea or Man utd. Even if you take the Flamini of two years ago - he was competent at DM, competent at LB and RB. Which squad will not want a player like that? Now, he is superb at DM, which I always thought he would be. It's Arsenal's loss, any way you look at it.

Now the reason I think he moved is this - Vieira's performances in Italy over the last 2 years do not come close to Flamini's, yet Vieira is first pick for France. What will they say when Flamini goes to Milan and outshines him week in, week out? Flamini's reputation will skyrocket. Have you heard what they are saying about Momo Sissoko over there? Sissoko is suddenly a huge star in Italy. This is a player who could not even trap ball at Liverpool.

Firstly, it is not my write-up. I don't write editorials, only news stories. I think it is a good write-up though.

I think Flamini will be a star at AC Milan. His name will be recognised as much as Patrick Vieira's and he can cement his France spot. No matter how long he stayed at Arsenal, he would never have been one of their top stars. However, if you look around Europe at the big name players in his position - Yaya Toure, Seydou Keita, Makalele, Mascherano, Vieira, Cambiasso, Diarra, even Toulalan - they all have big names and stellar reputations - which Flamini does not. I think it is time for him to take his place amongst these so called big names because he is every bit as good as they are. I don't think he would have got that recognition at Arsenal because he will always have that 'squad player' tag attached to his name. You also have to understand that his father is Italian so in a sense, he is going home.

I think the same applies to Alex Hleb. He is a top midfielder whose name can be mentioned with the best - but it is not. I think he can also cement his reputation in Italy. I am not dissing Arsenal but I think certain players there are very much underappreciated in terms of their reputation and image. IMO, Alex Song is another great player who can easily replace Flamini - we saw at the African Nations Cup how he single handedly held down Cameroon's midfield with great tactical awareness and wonderful passing ability. But if he replaces Flamini and does well, will he get the recognition he also deserves?

^^^^Hehehehehehe . . . . . . . . . what do you expect from The Sun? Maybe you should switch to goal.com. They have the best European news and transfer info.

As for Ballack, I am sure he still has two years left on his contract. Is there any reason to give him a new one? These big £100k+ contracts should stop when a player is 32 (which he will be in a year). After that, you offer him yearly contracts based upon his performances.

My brothers, how una dey? I'm a fan of you guys football even though I support Chelsea and I like to discuss football with anyone, regardless of their club. What do you guys think of this article?

[center][size=14pt]Arsenal Fans Must Blame Wenger, Not Flamini[/size][/center]
Arsene Wenger has mishandled the Mathieu Flamini situation, and sent a very dangerous message to the rest of his team, writes Abhishek Thakur,

Only three years ago, as Arsenal prepared to move to The Emirates the following summer, the headlines were dominated by the fact that Thierry Henry was moving into the final 24 months of his contract.

Attempts to get him to sign on sold newspapers throughout the season, and it was public knowledge that he would be on his way to Barcelona if he did not.

He did eventually commit in an emotional moment after the Champions League final – a decision he was to reverse the following summer – but the astute Wenger had taken no chances as far as the club's future was concerned.

The key point is that he understood the importance of the moment – they needed their skipper and star player as they moved to a big stadium and into a new era. He broke the trend, and Arsenal's wage policy, to hand the Frenchman a mammoth five year deal, one which put him at par with Andriy Shevchenko and Michael Ballack as far as the rich list went. Smart move.

As Henry was signing, a certain Mathieu Flamini was moving into his final 24 months. Did anyone even care?

What You Did Last Summer

Fast forward to last summer, when Flamini was moving into the final 12 months of his contract. He was, once again, conveniently ignored. What was 'the professor' doing? He was getting Cesc Fabregas – who had light years to run on his deal – to sign a massive extension through to 2014.

So, before one demands loyalty from Flamini, one has to ask whether Arsenal were loyal to him. If that was business, so is this. The only reason he was not offered a new deal was because Wenger thought he was expendable at that point. He might as well have been shown the proverbial finger.

Put yourself in Flamini's shoes for a moment. Would you grudge him for feeling treated like a second rate player? You move into the final year of your contract and watch as a teammate signs on for seven seasons. The person who has to answer for this is Wenger. The Arsenal manager knew full well what he was doing, and it is he who must carry the can, not Flamini.

Personally, I strongly believe that the hugely improved midfielder should still have stayed at the club. He will never mean to Milan what he could have to Arsenal, just like Henry will never mean to Barcelona what he could have had he retired at the Emirates. But that is a moot point.

What About Last Month?

Let us move on, assuming Wenger took a calculated business decision, and assuming he thought he could get Flamini to sign on. Let us now look dispassionately at what has happened over the last month. Let's talk business.

Within six months, the midfielder's stock had risen, and with that the interest of other clubs – particularly as he was available on a free. That was the risk Wenger had taken.

Flamini's agents advised him to hold out for a meaty offer. Wenger was to refuse, and made it very public that he would not be blackmailed into breaking his wage policy – the very policy he had broken to keep Thierry Henry at the club.

Another finger, only this time, the player decided to respond in kind. Within six hours of Arsenal's final game, he was in Milan, and another 18 hours later, he had completed a medical and signed on for four seasons at around 4 million euros per year (equivalent to around ₤60K per week). Supposedly, Arsenal would not go beyond ₤50K.

I would rate Flamini at around ₤10-12 million today, even if I was to be conservative. Now, Wenger will go into the market, and probably spend at least ₤8 million as he looks to shore up his midfield again. Flamini, in that sense, would have been a free-transfer, so that eight million could easily be amortised into an extra two million over four seasons.

Even from a purely business perspective, it makes no sense to let him go and then spend more money on a replacement. If Henry earned in excess of ₤100K, surely Flamini could have been offered more than ₤50K as a player effectively signed for free. There have been some great French mathematicians in the past. Arsene clearly doesn't tow that line.

What Message Does This Send?

And the most concerning bit is yet to come. In doing all this, Arsene has broken up a midfield partnership that was perfect for the way he likes to play his football. We have seen some absolutely amazing stuff from Arsenal this season, and a lot has to do with how Flamini has combined with Fabregas. Arsene must now strive to recreate that from scratch, with a player who may or may not suit Cesc's style.

What is more, by losing a key player, he has sent a very dangerous message to the rest of his team. With a new deal for Flamini wrapped up, today, he would have been thinking of consolidating for an even stronger assault on Manchester United. Every Arsenal fan would have been thumping his chest proudly.

Instead, he has told Cesc Fabregas, Emmanuel Adebayor and Alexander Hleb that he is unwilling or unable to do what it takes to keep this team together. Nice way that to demand trust.

The likes of Barcelona, Real Madrid, Inter and Milan interested in one or more of those players, who will surely have been disillusioned somewhat by the developments. Reports this morning already claim that Fabregas is unsettled after Flamini's departure. Real Madrid circle over him, while Inter refuse to give up on Hleb. The chest thumping fan has been replaced by a worried one!

'Hey gaffer, if you care so much about building a team, why did you not keep Flamini?' That could so easily be the refrain, one that Wenger might struggle to respond to as mega offers start coming in. There will be teams willing to offer Adebayor and Hleb ₤80K per week, and Madrid and Barcelona would probably hand Fabregas a bumper ₤120K. Worrying times at The Emirates, and of their own doing.

Be it lopsided priorities last summer, poor mathematics last month, or simply a sloppy estimation of the damage this exit could cost, there is only one person who must answer for this. So, before Arsenal fans abuse Flamini, they must ask their professor how he managed to land the club just where they were two years ago.

To conclude, what would have been a summer of strengthening for Wenger now threatens to turn into three months spent desperately trying to hold on to his key players. This desperation was already evident in some of his comments about Adebayor on Monday, as well as his anger towards Ramon Calderon.

Talk about swinging the axe onto your own foot! Sorry Arsene, but you have got this one completely wrong.

Man Utd have this week made an enquiry for Palacios of Wigan. I guess they are trying to unsettle him before their match on Sunday. Same old Alex Ferguson.

Anyway, this is what Steve Bruce is saying about the match:

http://www.goal.com/en/Articolo.aspx?ContenutoId=686547

In the buildup to Manchester United's must-win game at the JJB Stadium, Steve Bruce has scoffed at the suggestion that Wigan will be anything less than fully motivated seeing that their Premership status is now assured.

The former Red Devil stands in the way of Sir Alex Ferguson's tenth Premier League trophy, but he was keen to point out that there is huge financial incentive for his club to finish as high up the table as possible, as a result of the prize money designated for each league position by Premier League before the start of each season.

"We've got to be professional and we will be. The difference between finishing two places in the Premier League these days is almost £1.5 million," said Bruce.

According to the number crunchers, if the Athletics, who currently lie 13th, beat United and Newcastle United lose at Everton, they would finish 12th, earning them £6.4m in prize money. But, conversely, if the Athletics should lose they could finish as low as 15th and net £2.1m less.

Meanwhile, Wigan are hoping to seal the deal for Egyptian striker Amr Zaki, who Bruce personally traveled to Egypt to watch in action over the weekend.

Is this a good idea?

[size=14pt][center]Ballack To Receive Bumper Deal[/center][/size]
Chelsea midfielder Michael Ballack will be rewarded with a lucrative three-year deal following an outstanding season at Stamford Bridge…

The Blues are keen for Ballack to commit the rest of his career to the club, and he is likely to accept despite strong interest from Real Madrid and former club Bayern Munich.

The 31-year-old got off to a slow start at Stamford Bridge, initially struggling to cope with the pace of the Premier League following his free transfer from Bayern in 2006, and had a rocky relationship with former Chelsea manager Jose Mourinho.

However, the Germany captain has flourished this season under new boss Avram Grant, and has become the key creative and attacking element in a star-studded Chelsea midfield, scoring nine goals since his return to action late in December.

And it appears Grant may look to reward Ballack’s excellent form not only by improving on his current ₤121,000 deal, as the Israeli is considering a shift to a 4-4-2 formation so as to best utilise Ballack’s attacking talents and accommodate striker Nicolas Anelka.

But Grant have to find a new strike partner for his formation is reports regarding Didier Drogba’s imminent exit are to believed, as the Ivorian is supposedly frustrated with his paltry ₤100,000 pay packet and feel under-appreciated at Stamford Bridge.

But plans for next season must wait until the current one is dealt with, as Chelsea look to secure what would be a memorable double.

The Blues are battling with Manchester United on both domestic and European fronts this season, as they lie level on points heading into the last game of the Premier League season and are set to face each other in the Champions League final in Moscow on May 15.

And although United’s superior goal difference makes them favourites to clinch their 10th Premier League crown, Ballack has experienced first-hand with Bayer Leverkusen the pressure involved in maintaining a slender advantage toward the end of the season.

“Everything is in United's hands and the pressure is all on them now,” he said. “With Leverkusen in the last game, we needed just a draw and Bayern Munich needed to win and we lost. It was even against a lower team in the league, so I know that anything is possible and this is possible.”

Chelsea face 16th-placed Bolton Wanderers this weekend, while the Red Devils face 13th-placed Wigan Athletic.

And Ballack is adamant that United will be tested, as the Latics scrapped 1-1 draw at Stamford Bridge recently thanks to a late Emile Heskey equaliser.

“We hope that Wigan play with the pride we know they have,” Ballack said. “When they played us a couple of weeks ago, they put four strikers on the pitch in the last four or five minutes to get something from the game. I hope they are not on their holidays.”
