i was able to take the first one to the point of integrating 1/2 of it..the half i couldnt do with the knowledge from the class is 4(1/2(1-cos 2x))^2
i dont know what to do from here
ok, i thought i knew what i was doing, but apparently not
also, we cant use u substitution, or chain rule, or anything too advanced
1. f(theta)=sin (2(theta)) from 0 to pi/2
2. f(theta)= 1 + cos (theta) from 0 to 2 pi
any and all help is greatly appreciated!!!!
thanks in advance
