Graphs of trigonometric functions

Check or uncheck the box next to a trigonometric function to show (or hide) its graph. This will also show the corresponding length on a right triangle with one vertex on the unit circle.

Move the red point around the unit circle to see corresponding point on the graph; the x-coordinate is the angle, and the height is the corresponding (signed) length.
