The package is built for use with PSTricks. It provides macros for plotting and manipulating various mathematical functions:

• polynomials and their derivatives,

• Fourier sums,

• the Bessel function defined by its order;

• the Gauss function defined by sigma and mu,

• Bezier curves from order 1 (two control points) to order 9 (10 control points),

• the superellipse function (the Lame curve),

• Chebyshev polynomials of the first and second kind,

• the Thomae (or popcorn) function,

• the Weierstrass function,

• various integration-derived functions: normal, binomial, poisson, gamma, chi-squared, student's t, F, beta, Cauchy and Weibull distribution functions and the Lorenz curve,

• the zeroes of a function, or the intermediate point of two functions,

• the Vasicek function for describing the evolution of interest rates,

• implicit functions.

The plots may be generated as volumes of rotation about the X-axis, as well.
