Default Calculus freaks...I need help!

Alright so I'm doing some Calc II homework and I'm stuck on these two problems. I really don't have any idea where to even begin. Assume that ][ means integral. They are..

1) ][ e^2x cos e^2x dx =

and

3) ][ x^2 / (1 + x^6) dx=

I'd really appreciate any help guys!

1 (1/2)sin(e^2x) +c

3 (tan^-1 (x^3))/3 +c

on the first one, let u = e^(2x), so du = 2e^(2x)
