Hire english tutor 4 her nau..u will be doing her a big favour

nah, what she needs is someone who speaks and understands both English and French.

Antoinne:
Guys, I've been a bit busy out of here. Hence my frequent absence. However i have an idea i think we should all talk about.
With this combined knowledge and effort at helping people solve problems, creating maths problems, and encouraging discourse, wouldn't it be nice to take this to a completely different platform and create some kind of "online business" out of it? Just wondering...

agentofchange1, Seamione, dejt4u, Karmanaut, jackpot, and others I've failed to mention.

like solving people's assignments for a fee?

@PunkyVeer
you've seen Durent?

the post didnt match the title

scores?

lol

If 2Baba neva fucck that gal, make I bend

Porthos:
jackpot, richiez, agentofchange1 ………… should i believe him? is he right?

you see someone using a powerful terabyte computer (probably, Wolfram Alpha) to solve maths and you're asking whether to believe him.

Who am I, abeg? I trust that computer more. Believe him, FFS!

masperano:
*Smiles* see who is talking because of the small small sec school/undergrad maths wey u dey solve na im dey shark you abi?

yes sir/ma. I do know it means throwing curved balls.

PS: when replying me next time be more civil

by your reply, you're the most civil. Miss/Mr Civility 2015

masperano:
Perhaps u should have added it up. So for instance 24+12=36 and then divided by 60 which will give you the required 3/5(a bit tricky).

not everything you see in a textbook is correct. The high time you realize that, the better.

Required ko, requested ni.


The answer to that question is 2/5. I can bet my lunch on that.


btw, do you know that ''tricky'' means intended to deceive?

personal59:
I can use laplace to some extent cos I apply it in chemistry very well (am a chemistry student)
But wouldn't expect it sha cos he never teach us that

wow. What's the application to Chemistry?

agentofchange1:
c'mmon bro, the question says no repetition

5C3 means total number of ways we could form the 3-digit number without repetition

421 (124) ,521(125) , 621( 126) already exist in the sample space.

Let me follow your argument to see if it holds water:
you gave your sample space as
S={(124),(125),(126),(245),(246),(145),
(156),(645),(641),(265)}.

Following your logic,
S={(124),(512),(126),(524),(246),(514),(156),(564),(164),(526)} because, for instance, 125 and 512 are the same numbers without repetition (whatever that means).

So, probability = 0/10=0.

Contradiction!

Class dismiss. Everybody go home.

Seamione:
You're absolutely correct and on point madam

wow. I'm not always sure of this topic.

Seriously, na just brain I dey use answer Permutation and Combination problems. I dislike questions that I gaze for like 10 mins before attempting the solution. I prefer to start putting something down the first minute I look at the question, even if it will take me 30mins to solve. I call it Solution Assured.

personal59:
Thanks bro I do but it can't compound it cos I know other topics very well they are variable seperable, homogeneous, exact, all ODE so I know those ones very well so I just want to solve this four, know it and do it all who know what his compulsory question would be so I need to play safe too. But for other topics I av no problem with them
Just help me to solve the question I would b able to comprehend it

my left mind is wishing the guy drops Laplace Transform as the compulsory question

agentofchange1:
Aright dear i get your point,


BTW: look into that probability question i solved in the previous page , your honest mathematical input is required. tnx.

that question is the same as ''probability that it is an odd number.'' probability= event occurence/sample space.


We have three boxes to be filled with the figures 1,2,4,5,6 without replacement. The last box only has 2 choices 1 and 5.
So, if the last box is 1, then we feed the other two boxes with 4 figures. No of ways this can be done is 4P2=12
Occurence= 4P2*2=24.
Sample space is 5P3=60

probability = 24/60=2/5.

Hmmmmmmmm. Someone should correct me, please.

Karmanaut:
x^2/a^2+y^2/b^2 = 1
(assuming semimajor axis length a, semiminor axis length b, center (0, 0), and rotation angle 0°)

The center h, is given by:
(cd-bf)/(b^2 - ac )
The center k is given by:
(af -bd )/(b^2 -ac)

where d, f are gotten from the quadratic curve

a^2 -b^2 = c^2 where c is the focus on either side.

Sleepy....

ok, it is after 8 already.

Brother, wake up wake up wake up

agentofchange1:
ur own na 2 just dey post problems n tag people but u scarcely help others in solving dias

i could av post solutions to some of ur problems even if i av limited ideas cud av done all possible .

but feels lazy/discouraged to do so

ok. Thank God you said scarcely, not completely. My time here is somehow irregular. Most of the times, I come to see new questions and solutions. If I see an unsolved one that is not too trivial and interests me, then I'll go for it. Questions like Perm and Combination, simultaneous solution of 4^x+6^y=100 and x+y=5 do not interest me.

Some of the questions that I post is for others to learn. Under normal circumstances, elementary university maths treat conic sections at the surface level. That question requires knowledge of rotation of axes. You'll agree with me that sometimes we do have an unnecessarily long solution. In other words, i'm looking for shorter solutions, that is why I seek for other people's POV.

Don't feel that you're doing me a favour by solving the question. It is not about me. Other peoples are learning too. Gracias.

benzion72:
That is exactly the way I felt when I got Executive trainee job with a bank in 2001. I resumed 24th December, 2001. Here are my unsolicited advise for you. You don't need to pay a dime for it. Get the book The richest man in Babylon. It major advise is to save 10 percent of your income, invest another 10 percent and give a tithe of 10 percent. I will advice you invest 40 percent of your income in anything that will give you financial freedom and landed property is the best for now. You don't need to go to Lekki go to Mowe Ofada redeem. Intact if I were you I will invest little in electronics, phones etc because they change with time. It reminds me of my BlackBerry Bold 1. Brand new one then cost N110,000 today it is less than 10k. That money can get me an hacter of land in Ibadan 8 plot then and today I would have resold it at least 300k per plot 7 years after. Have an alternative plan called plan B. Wish best of luck

good

Karmanaut:
Solution: Foci: (2/√3, -2/√3)
Vertices: (√2, -√2)
Center: (0,0)
Semi major axis length: 2
Semi minor axis length: 2/√3

please, kindly show full workings.

Show that the curve x²+xy+y²-2=0 is an ellipse. Hence, obtain it's
(i) centre
(ii) vertices
(iii) co-vertices
(iv) foci
(v) axes of symmetry
(vi) semi-major axis length

yes dear

It might feel so, but one needs to consider the risk and pains involved. I'm a believer, I believe in miracles.

But truth be told, this is a terrible thing to go through...the ridicule, shame and all that

agreed.

[s]Such things might be product of drugs taken to abort the baby's life before deciding to keep the pregnancy.[/s]

This is quite sad.

Twaci:
Ok, dont see it from the parents viewpoint....

Say u are the doctor in charge, would u advice its parents to kill it?

i found this offensive.

benedima1990:
Go study your compound interest formular well

Those mathematicians above me

It's not interest at the end of 20 years oooo

But each year.

So for every year, 12% of the amount saved will be added to the principal. Thereby moving the total forward to the next financial year *


I love mathematics

It is not even pure compound interest because you have to be adding the savings continuously.

Well, the amount to be carried forward to the next year includes the Old Principal+Interest+Savings. It's more of compounding an ''ENFORCED'' principal.

I need this same info too. Any idea, peeps?
