Algebra 2 Lesson 7.4: Graphing Sine and Cosine Functions

This lesson covers the basic graph of the sine and cosine function. We cover graphing these functions using technology (Desmos graphing calculator). We also identify key features of the sine and cosine functions, such as period, midline, amplitude, and frequency. Lastly, we quickly review how to determine the average rate of change.

*Error around 9:35 on frequency. The frequency as defined in the video is not the number of cycles within the period. To find the number of cycles, you multiply the frequency formula given here by 2pi, and this gives you the number of cycles from 0 to 2pi.*
