Sine and Cosine Graphs from the Unit Circle
Drag the angle slider slowly and observe the graphs of the sine and cosine functions.
Each point on the f(x) = sin(x) are made up of two pieces of info:
x: angle in the unit circle
f(x): the height of the triangle in the unit circle
Each point on f(x) = cos(x) are made up of two pieces of info:
x: angle in the unit circle
f(x): the width of the triangle in the unit circle
