PostScript lacks a lot of basic operators such as tan, acos, asin, cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). Also (oddly) cos and sin use arguments in degrees.

Pst-math provides all those operators in a header file
`pst-math.pro` with wrappers `pst-math.sty`
and `pst-math.tex`.

In addition, sinc, gauss, gammaln and bessel are implemented
(only partially for the latter). The package is designed
essentially to work with pst-plot
but can be used in whatever PS code (such as pstricks `SpecialCoor
"!"`, which is useful for placing labels).

The package also provides a routine SIMPSON for numerical integration and a solver of linear equation systems.
