Jaynim: A trader bought 30 articles.He sold 20 of them at a gain of 16% and sold the remainder at a loss of 4%.Find the percentage profit/loss on the articles.

It's 9.33% gain

otokx: You can pay in any of the banks there in lagos.

All right, thanks Sir.

Although I haven't downloaded the practice questions, from the comments here there must be something wrong with the practice question on maths. Unilag has started it again just like last year most of the practice questions on the part 2 of maths were wrong hope others are very correct? Hmmmm. . .

engr lucky: If not that I'll be in Lagos when you'll be in PH, I'd taken you to one St. Bottles Cathedral of mortuary standard to maintain some ACH and Nkwuobi after your exam.

Yeh. . .Jesust! That'll be so nice of you boss, dont worry i'll wait till you return. I'll be spending two weeks there. . .that joint sounds good, I hope it's the best?

Thank goodness, one of my bosses finally locates here. . . .welcome Mr. Calculus

Please can I pay in any of the banks stated on the slip here in Lagos or it's only sold over there at Uniport? Please reply as soon as possible. . .thanks

Thank God for you too bro. I was given to know that the ratio of the annual intake of first to second choice is 80:20, I'm afraid. Though to me, it's like going there to visit and squat with one of my brothers for sometime notwithstanding, I'm optimistic . All is well

I'm nw here with u guys 2 learn, 2 solve n 2 help. @ omosive, my mentor always tell me d@ nothin is impossible nt until i found myself knwing basic maths n 4rm there I tank God, so u cn do it, a question may take u 5 days 2 tink, buh if u give it 2 another person 2 solve, d@ shows u dnt wnt 2 disturb ur brain. @ Ortarico, calculux, More PALMOIL 2 ur elbows. Lols. Letz drive mathematics pls

hmmmmmm. . . .thanks.

Calculusf(x):
...kudos to my oga at the top(ortarico) for number one...2...integral dx/sqrt(x-2)^2 +25...using the principle of hyperbolic functions...{1/sqrt x^2-a^2 will attract cosh,1/sqrtx^2+a^2 will attract sinh,1/sqrta^2-x^2 will attract sin}...so from those standard integral...sinh fits,then back to the question...integral dx/sqrt(x-2)^2+25...let 5sinh@ be x-2...therefore the equation becomes integral dx/sqrt(5sinh@)^2+25...integral dx/sqrt25sinh^2@+25...NB...don't forget x-2=5sinh@...so,integral dx/5sqrtsinh^2@+1...(pause)...using the principle of hyperbolic functions cosh^2@-sinh^2@=1...cosh^2@=1+sinh^2@...substitute that to where we stopped...integral dx/5sqrtcosh^2@...integral dx/5cosh@(pause)...from the beginning...x-2=5sinh@...dx/d@=5cosh@...dx=5cosh@d@...back to where we stopped integral dx/5cosh@...substitute dx=5cosh@d@...then it becomes integral 5cosh@d@/5cosh@...which is equal to integral d@...which is equal to {@}...from the top x-2=5sinh@...(x-2)/5=sinh@...therefore @=arcsinh(x-2)/5 +c...

That's my boss. . . .always reliable, me hail oooo

I want to take the time to thank my oga at the top; Sir Labodinho for his assistance in spite of the unfamiliarity.
Guys, Oga Laboz is someone that can be trusted. God bless him for me.

Zico0: Please who can integrate these derivatives:
integrate tanxdx

integrate 1/_/(x - 2)^2 + 25dx
i hope it is comprehensible.

1. NB: $ denotes integral
$ tanx dx= $ sinx/cosx dx
u= cosx then we find du= -sinx dx
substitute du= -sinx, u= cosx.
$ sinx/cosx dx= - $ (-1) sinx dx/cosx
=> - $ du/u
solve the integral:
=> -In|u| + c
substitute back:
u= cosx
=> -In|cosx| + c
OR
$ tanx dx= -In|cosx| + c
=> In|(cosx)^-1| + c
=> In|secx| + c
Therefore:
$ tanx dx= -In|cosx| + c
=> In|secx| + c

Jaynim: 10

That number five, you sure sey na 1? Remember sey na Niger and Chad, though Chad na North-East but still North.

labodinho: U'r welkum sir,morning to u all.

Mr Calculus: no na oga ortarico......uniben thresd is bouncing bro

All right bosses.

Mr Calculus: wow...i have really missed alot..
Greatinz 2 all d generalz in d house@oladimeje,ortarico,lurve,farano,hillsnite,dr asiko,omosivie,rashywire,engr lucky,laboz..e.t.c..my respects sirs nd madams

My oga na wah for you and calculusf(x) ooo. . .una jus leave us for here totally. Anyway, how uniben thread for there? @oga laboz, thanks in advance ooo. . .i'm grateful boss.

Omosivie,:
Oh!!!!!! Someone told me that it's d best, that's why i bought it sha. Pls i'm having a little problem with mensuration, circles, bearing and lines. Can u help me out with them cos i don't understand them @ all. Are u on 2go?

Yes I am. You can add me with 'oketunde2' and/or my boss; calculusf(x) with 'mathemagician'.

hillsnite: hmmmm... Bt dere u r wrg...were r nt dealing wif cm again..we r dealing wif cm^2... So it shld b 0.025

You're great bro, thanks for the observation but 0.026m sq instead. . . .@farano, you can see that that your book is the one needing update.

@farano:
I don jam o. D solution was wat i saw in dat textbook pls. Dr genius may hlp us wif dat.

That your textbook needs update oo. . .tinz don change, we're in the 21st century. Dr. Genius can confirm that!

hillsnite: e options were all in cm... And d final answer is suppose 2 b in m^2. I guess 100cm = 1m.... If it so..d answer obviously cant b 255

Little error there bro she didn't say it's 255 now, she said it's 2.55m sq. So the area of a triangle of sides 22cm, 24cm and 28cm is 254.8238cm sq. So converting 254.8238cm to metre:
100cm = 1m
:. 254.8238/100 = 2.5482m
Appro. it to the nearest metre: ~ 2.55m sq. . . .hope it helped?

Omosivie,:
Lamlad Maths text book

Hmmn. . .i've heard of the book before but haven't seen it. I doubt it's authenticity, maybe another person here should try helping.

hillsnite: i disagree wif ur number 7 and 5

What's wrong in no 7?

@farano:
9/10. dat nomba 7 suppose to b in square metre. Nomba 5 correction: 20 floz = 1pit.......... 1floz = 1/20pt.......54floz =(1*54/20)pt=2.7pints

Hmmmn. . . At number 7, my answer was in metre square (m sq) look at it well.

On that number 5 correction, plz where did you get that measurement from (20 flo z = 1 or 0.05 pint)? cause the one that is generally recognised and acceptable is US metric which says:

16 US fluid ounces (fl oz) = 1 or 0.0625 pint
8 pints = 1 or 0.125 gallon
2 pints = 1 or 0.5 quartz
4 quartz = 1 or 0.25 gallon
128 fl oz = 1 or 0.0078 gallon

Using 16 fl oz = 1 pint
=> 1/16 x 54
=> 3.375 pints

@farano:
hmmm,some tear race 4 dis elementary question! lol. Ortarico where u dey nah?u neva reach ur aus? Yemmy,i no fit shout sha,@ eni orisha u fit tell unilag on 22nd u no b maths guru?lol. Well,dis d correction. 1) 23.9113m 2) 9.531m 3) 72.3t 4) 56pints 5) 2.7pints 6)43.63cm^2 7) 255m^2 17cm 9) 5.8cm^2 10)506cm^2

Suntin wey me don do b4 u post ya basic 16 correction, mark me ooo. . .e no tay me enter house, everyday hustle!
