Learn Trigonometry with JavaScript

We study trigonometry by implementing an interactive tool in JavaScript. We learn several trigonometrical functions like the sine, cosine and tangent (sin, cos, tan) and their inverse functions: the arcsine, arccosine and arctangent (asin, acos, atan). We define these functions using a right angle triangle at first and then extend the definitions using the unit circle.

We practice these functions using JavaScript in a way that hopefully makes them more clear and useful. Check out more videos like this:
