Notes | Graphing sine, cosine, tangent, cotangent, secant, and cosecant To begin the activity I had drawn on the board a graph in blue for the basis of the graph of sine and cosine. I had the students, groups of 4, find the sine in one and the cosine in the other. They found them in increments of 30 degrees. They then went to the board and plotted the results on the graph. They each had a different color for their graph so we could tell which one was sine and cosine by sight. The students had never seen a sine or cosine graph before so they had no idea what it would look like until all the plots were done. |
