Every time I think I can't live without an inverse trig
function, I end up finding an approximation that gets
me near enough to it without the fuss of actually
having to use them.

Most of the time, I am able to approximate them close
enough with a simple linear function, but if that is
not good enough, the lookup/lookdown functions can give
about as complex of a function as you could want or
need.

Finally, if you HAVE to have it, simply devote the EEPROM
space to defining ARCSIN, ARCCOS and ARCTAN.

It would use up 3/8's of your code space in each
programming slot you need the funtions, but this would
not be too hard to manage if you break your code up
into several slots. I think you could do it if you really
needed it.

Just my opinion. I have been wrong before (once ;-)
