Trigonometry for Flash: A Visual Reference

Published on Tue 12 Aug 2008 by Will

Trigonometry is something any aspiring Flash developer should learn. It is the cornerstone of becoming better at manipulating graphics purely with code.

I am certainly not a math guru by any means. I often find myself having to flip through a book or dig through previous projects to find the formula for getting the angle of a vector or the distance between 2 points etc. So I have created an animated reference to trigonometry within the Flash coordinate space. This is very much for my own reference but I think others will find it useful.

As stated this is a reference, not a detailed tutorial. If you would like to learn more about trigonometry in Flash i highly recommend Actionscript 3.0 Animation and Advanced Actionscript 3.0 Animation by Keith Peters.

This content requires Flash.
