You could let Make the subs and get: Now, we can let Make the subs and it whittles down to: Resub for That gives us: Resub for and get:

I got the integral of (sin(t) +1)^2 then that becomes sin^2(t) + 2sin(t) + 1 the integral of sin^2(t) is 1/2[1+cos(2t) how do I make that in terms of 't'?
You coul How did you get to there? how does sin^2(t) go to 1/2sintcost?
