That's ok. Yeah, the answer is A. You'll use the graphs of cosine and sine quite often, so check this out. http://www.mathsisfun.com/algebra/trig-sin-cos-tan-graphs.html When you have free time, you should take 10 minutes and read up on that. I know spending your free time on math doesn't sound fun haha, but trust me, it will make like a lot easier. Once you get to trig and further, you'll use them all the time.
