    mmm... looks like you have no idea of what's going on, since you don't seem to know how to ask a question properly...because you question seems trivial... my guess is that you can input that into a calculator and remember to use the "degree" mode.. then you will be fine. easy :smile:

    Moved from Advanced Physics to Intro Physics. rasikan, what do you know about trigonometric functions? Are you allowed to use a calculator on this problem, or are you supposed to use some other method?
