Thanks, as a programmer (re)learning math and trig this will be a good exercise.

  Totally agree. I recently had to do the same thing (relearning H.S. trig) using the HTML5 canvas. It would be an interesting exercise to take this example and add a draw_arc() function.

  For me, at least, graphics was the way to learn trig in the first place. I wanted to make a thingy on the screen go at a specified angle at a specified speed, so that I could change its angle without changing the speed, and I vaguely knew that this had something to do with sine and cosine, so I took a trig textbook off the shelf and puzzled it out. Didn't need things like the double-angle formulas, though, so I didn't learn those until I took a class that covered them.

  Nice to hear. Go ahead and do write a program. If you have any issues with it, or have trouble following anything that is written in the article, send me an email and I'll be happy to help you out.
