I had to define many of the mathematical functions for this stack. If you look in the stack's script you will see how I defined each function. Some of the functions take a noticeable amount of time to be computed if your Macintosh is running on a 68000 processor with no math chip. (That's what mine is doing.) A faster clock speed and the addition of a floating point math chip (like the new Mac SE 030 and Mac IIcx have) would probably do wonders for computation speed.
I shortened the name of some of the Hyperbolic and Trig functions to match the style of HyperTalk. For instance, HyperTalk abbreviates the ArcTangent(x) as atan(x). So I abbreviated the
