for the sake of convenience, I'll call the integration sign ... (you know, the sign that looks like a giant 'f' or distorted 's')
find primitive of (sinx)^2
(sinx)^2dx
=1/2(1-cos2x)dx
=1/2(1-cosu)(1/2du)
=1/4(x-sin2x)+C
the answer at the back of the book was (1/2)x-(1/4)sin2x+C
I dunno where I went wrong, help!!!
