Hello!
Today we spent a lot of the hour on trying and understanding how to graph one cycle of sine and cosine. Some big take-aways from today are (1) how to graph, (2) how to label the graph based off the period, and (3) what the difference is between a sine graph and a cosine graph.
The video here can help you with graphing sine and cosine too.
I’ll be checking in the homework on Monday. We will have time tomorrow to work on it in class too.
Go on and conquer!
