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

Completing the square we get
Can you go from there?
I got the integral of (sin(t) +1)^2
then that becomes sin^2(t) + 2sin(t) + 1
the integral of sin^2(t)
how do I make that in terms of 't'?
How did you get to there?
how does sin^2(t) go to 1/2sintcost?
