Question

integral of (t^2+t)/(sqrt(t+1)) using u-substitution

Answer 1

Bah, moving to here, that chat thing sucks on my computer. But yea, I'd let u = t+1 and do the factoring

Answer 2

So int of (u-1)(u)/sqrt(u)

Answer 3

Then it's (u-1)(u)(u)^(-1/2)

Answer 4

From there you can easily simplify it and break it into 2 managable integrals.

Answer 5

right okay thanks, I had thought about factoring the numerator but didn't use the factored bit right is all

Answer 6

Ah, okay. Well good luck. Post if you need more help (although I'm gonna be leaving soon)
