Question

with the integral of x/(1-x^2)^3 use u substitution to find what it is, i get the answer but it is reverse the fraction should be on top but its on the bottom, please help the answer it 1/[4(1-x^2)^2] and i get the reverse of that

Answer 1

Let's see.

Answer 2

What did you use as your substitution
?

Answer 3

Is that what you got?

Answer 4

+ C

Answer 5

You mean 1/(4(1-x^2)^2), right anteater?

Answer 6

Yes :)

Answer 7

That's what I got as well.

Answer 8

i got that reverse for some reason , i thought that du would be on top
and u would be on bottom

Answer 9

It is. You can use 1 - x^2 as your u. Then du = -2x dx. So since you have x dx, that is -1/2 du

Answer 10

And then you have that over u^3

Answer 11

Hope that helps! Anteater gotta go :)
