You must show your procedures in order to receive any credit. You will not receive credit if you just write down an answer without showing how that answer was obtained.
Solution
u = 2x
du = 2 dx. We then evaluate the integral as follows: Z sin (2x) dx =
sin (u) du =
( cos (u)) + C =
cos (2x) + C.
d dx
cos (2x)
( sin (2x)) (2) = sin (2x)
shows that our answer is correct.
