lissajous: Lissajous polynomials

In mpoly: Symbolic Computation and More with Multivariate Polynomials

Description

The Lissajous polynomials are the implicit (variety) descriptions of the image of the parametric map x = cos(m t + p), y = sin(n t + q).

Usage

lissajous(m, n, p, q, digits = 3)

Arguments

m, n, p, q	Trigonometric coefficients, see examples for description
digits	The number of digits to round coefficients to, see round.mpoly(). This is useful for cleaning terms that are numerically nonzero, but should be.

Value

a mpoly object
