I'm not great when it comes to integrals. I have Sin^2(2x) I know Sin(x) goes to -Cos(x), and Sin(2x) would go to -Cos(2x)(2), right? I just don't know how to approach Sin^2(2x) thanks

I have a follow up question. Doing a seperate part of the same question, I have xsin(2x) Would this be [(x^2)(-cos(2x)(2)]/2 ?

Sorry, I'm taking calc + calc II as summer classes.. it's all going very fast. I'm having a hard time keeping up.
