The Palm operating system doesn't include high level math functions for
trigonometry, etc. However, there is a free shared library you can use
called MathLib (http://www.radiks.net/~rhuebner/mathlib.html). It is quite
common for Palm applications to require this shared library in order to
function. The distributions typically include the MathLib.prc file with the
application prc file, so you can easily install both. The advantage of a
shared library is that the code doesn't end up getting duplicated in each
application that uses it. Your application will need to find the library
when it starts up, and give a suitable error message if it can't find it.
