good, which is = 1/a^1/2 right?

hope u see wer am going with this

ayokunlei:
(a)^-1/2

IT happens

MathsChic:
Sometimes I just hate being smart. Being smart, getting A's in school will make you top your class and later provide you with a decent to very lucrative job that's just going to assure your future. You won't be poor and you'll live a comfortable life. But sometimes, I just can't help but wonder at how boring and mundane everything eventually becomes.

On the other hand, not getting all the A's and not topping your class will throw you out there, challenge you to dream big and force you to come up with a living that could probably break bounds, making you into a household name. Linda Ikeji, Toke Makinwa, Folorunsho Alakija, Oprah, these are people who certainly didn't get the best grades in school or studied the best courses at university, yet they shape and influence the polity more than the best graduating student in Electrical Engineering from the set 1985 in Unilag would ever do. And who's that best graduating student anways? I bet no one knows today!

I so hate being smart! I wish I was a regular one that would have had to create something for herself.

JESUS IS THE ANSWER.

if u have a^(1/2) /a , what does it simplifies to ?

ayokunlei:
pls cld you show the workings?

OK , That simplify to 1/sqrt(1-x^2) dx =arcsin(x) +c

ayokunlei:
No, the closed bracket is not included.
Sqrt of (1-x^2) is at the top of the former....

ok ,try use the parenthesis properly,

is it integral 1/[(1-x^2)sqrt(1-x^2)]dx ?

ayokunlei:
boss, i cant snap with my phone. Pls note: Multiplied by means 'dot', sqrt means square root, 1-x^2 means, 1-xsquared.

ok bro make ur question clear or upload a pix

ayokunlei:
Pls help - integral 1/1-x^2 multiplied by sqrt(1-x^2)dx. Agentofchange1,Thankyoujesus and others

No treading of insults plzz,,maths problems is all we solve here , tnx .

Durentt:
Yet u criticize mathematician nd compare dem to economists, why dont you use ur dumb engineering brain nd solve all ur math problem. Crystallised creatinous fvcktard

Q3 ( Check (*) ) above

here,

Timothy3113:
Pls help out

you are correct bro,

GreatYinkus:
@Timothy, thankyouJesus has done primarily all the work, but in case you need answers to cross check:

1. xSin^-1x + √(1-x²) + c

2. ¹/₈[(5/2)x-Sin4x+(3/16)Sin8x+(1/12)Sin³4x] + c

3. -√(1-x²) + c.
I just hope I've not made any mistake

gat all solutions here bt the network is too poor over here ,will upload later

ok

Orthega:
pls, let ur soln to be clear as that of timothy 3113. Ur kindness will highly be appreciated,tnx.

yes sir , off-course 2k is always even for all non-zero k

i will post an alternative proof Asap

DatechMan:
I must mention that some of this your questions, especially 1 - 3 need not be proved using Mathematical inductions because they are self sufficient.
Meanwhile check out agentofchange1 solutions. Ask questions if you are not clear


Q1
Agent of Change has tried to adapt the proof to Mathematical Induction.


Full proofs here. Check it out

http://www.artofproblemsolving.com/wiki/index.php?title=Proofs_of_AM-GM


Q2
agentofchange1 can you tell us why you think it is you have sufficiently proved the expression when the terms in the bracket cannot be said to be integers or Rational number to say the least.
Kindly expatiate. Because 2y is always even if only y is a non-zero integer.

Thanks

Sirneij:
No one to address these?
c DatechMan
cc Richiez

Sin inverse of what what ? make your question clear,better still upload a photo of it.

Meel:
I don come again, integrate $(sin2x)^6 and integrate sin inverse.

Q2

DatechMan:
Kindly write the questions on a paper and snap. The trig question is not clear

. [quote author=DatechMan post=41476789][/quote]

post questions on it,it will help more

dprinz99:
Pls can some one briefly explain to me the steps of solving partial fraction?
I have tried it my self Bt I'm gettin confused d more.
much tanks

Greetings all. nice works ....may contribute. soon ...
#Shalom.

check the question again , and edit Asap

cberryx:
Please someone should help solve this:

SOLVE BY LAPLACE TRANSFORM, THE EQUATION

d^2 X/dt^2 +10(cos5t - 2sin5t) given that at t=0, X=1 and dx/dt = 2.

At the end, the final answer should be this: (2t + 1) cos5t + tsin5t. I have not been able to arrive at this answer. this question is in page 91 of Advanced Engineering maths fourth Edition.

ayokunlei:
Thanks alot, God bless

its ok bro.. n bless u too.

BTW: check my solution on question 2

correct 'dy/dx ( ysinx) to. d/dx [ ysinx] ....(line 3 or 4)

twas a mistake ...' brain solves faster than hand. '

hope u get...
