This worksheet is designed to help students with graphing one cycle of the sine and cosine waves. It assumes they have a TI graphing calculator. I have found that students get a good sense of the rotational and reflectional symmetry in the graphs when they graph these sinusoids by hand.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
This worksheet is intended to be written on directly.
