Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 6
Trigonometry and Waves by Computer
Sine and cosine draw the same wave whether it is a swing, a sound or a signal on a wire. In this chapter you write programs that compute the trigonometric ratios, draw the unit circle and the graphs of sine and cosine, check every identity on thousands of angles, then add waves together to make beats and standing waves, and fit a sine curve to measured data. It goes with the chapters on Trigonometry, Oscillations and Waves, so each program checks what you learn there.
