Trigonometry

Sines, cosines, and tangents, oh my!

But there’s more: Use Desmos to easily graph inverse trig relations and functions, or to build interactive unit circles and sine wave tracers.

Get started with the video on the right, then dive deeper with the resources and challenges below.

Pro Tips

Easily switch between radians and degrees by opening the Graph Settings Menu in the top right of the graph.

Display pi labels on the axes by typing pi for the step of the axis.
