How do I graph amplitude and period of sine and cosine functions? I know how to find the amp. And per. but I cannot figure out how to put it on a graph!

The amplitude is the maximum value the function will return. The peak of the sin or cos function will have this y value.
The period is how often the function will repeat. Every 1 period the function will go through 1 entire cycle.
I'm not entirely sure what your question is. If you understand these concepts what is giving you trouble?
