Answer 3

Wolfram says it's arctangent.
So hmm I guess there is a nice simple u-substitution hidden in there.

Answer 4

\[\large\rm \int\limits \frac{t}{(t^2)^2+2}~dt\]

Answer 5

This looks really similar to one that you asked about last week :p

Answer 6

\[\large\rm u=t^2\]Get it now? :o

Answer 7

Oh yeah, I remember this problem again. I blanked out and didn't know how to start this one... again!

Answer 8

thanks as always!
