I have been having a trouble with this problem:
X / (4X^2+1)^2 dx<-------This is an integral that I have to solve using substitution
This is what I did.
So then I went back to original problem and plugged that in and got.
1/8*(1/(1/3)u^3) I got that from taking the anti derivative of x^2
I plugged u back in and got
1/8 * 1/(1/3)(4x^2+1)^3
after i simplify i get:
I would appreciate it if someone could tell me where i messed up. Thanks!
