Question

integrate (4x+3)/(x^4+4x^2)dx

Answer 1

You sure that's right, if it is it's not a nice one.

Answer 2

Yeah, I'm pretty sure. It involves arctan.

Answer 3

Eurgh.

Answer 4

I actually need more help with the algebraic manipulation.

Answer 5

I can't get it into solvable form.

Answer 6

I think you want to get the denominator into (x^2)(x^2+4) and split into partial fractions with denoms of x, x^2 and x^2+4. I'm not 100% that would work though..

Answer 7

That's not a bad idea, let me try it out.

Answer 8

Yeah, got it. Thanks!

Answer 9

Ace.
