Substitution u = x^3
Hi Guys,
I've been asked to substitute u = x^3 in the following integral int x^2/ (1+x^6)
Do I substitute by int x^2/(u^3) and have a scaler out the front?
or do I start by having int u^-1 / 1+ u^3.
Any help to point me in the right direction would be greatly appreciated.
regards
Brendan
