This Amplitude and Midline instructional video also includes:
Roll through two graphs. Learners see how the points from the unit circle allow easy construction of the graphs for sine and cosine using an instructional video. They discover how to find the amplitude and midline both from the graphs and the function in standard form. Pupils then graph sine and cosine with different amplitudes and midlines.
