Putting The "O No" In Trigonometry

I am writing a script that relies heavily on math.  Not just any math, but trigonometry.  As I have previously lamented, math is a personal weakness of mine, and I struggle to understand the functions on which I rely for this particular script to work.

Of course the script is not doing what I want it to do, because I do not understand its functions.  This has resulted in an evening of experimentation: I would change a line of code, compile it, run it and review the results.  This process was typically followed by muttering and more changes to the script.

Work continues on this script, and I am keenly aware of the time I spend debugging it.  This is update week, and time is running down.  Tick tock.
