Graphs of trigonometric functions

Desmos graphs

The sine graph

Here is the graph of y=sin(x). Drag the large orange point to move it along the graph. Click on any orange point to toggle a label showing its coordinates.

The cosine graph

Here is the graph of y=cos(x). Drag the large orange point to move it along the graph. Click on any orange point to toggle a label showing its coordinates.

The tan graph

Here is the graph of y=tan(x) with dashed lines showing the asymptotes.
