Sorry for the double post, I put it in the wrong section. I know this problem is very easy, I am just having so much trouble grasping the concept. I have to verify this problem and don't know where to start.
Any help GREATLY appreciated. Homework due at 3PM today.
Change eveything to sin and cosine, that should help.
