How would I integrate sin to the power of 4 ?
I can integrate sin², so I figured I could rewrite it as:
\INT (sin² 2x)² . dx
But now what?
I'm not looking for someone to solve this for me (although I do already have the correct answer with me), just to point me in the right direction..
Can anyone rewrite that in a form which would perhaps make it obvious of what I should do?
Surely there's no need to use the identity:
\INT u(dv/dx) . dx = uv - \INT v(du/dx) . dx
