Question

I came across this problem in my homework, and I was wondering if partial fractions would be rational for this problem.

Int [(2x)/((x^2)^2)]dx

If I don't use partial fractions, what would I use?

Answer 1

INT 2x/x^4 dx = INT 2/x^3 dx=-1/2 x^-4 + C

Answer 2

I messed up. I meant (x^2+1)^12
