This demonstrates Saunders plots of trigonometric and inverse trigonometric functions. Given a function at a complex number , the real part, imaginary part, absolute value, or argument of can be expressed in base as . A Saunders graphic shows the chosen digit encoded in the colors of squares centered at the corresponding complex -values.

function — the trigonometric or inverse trigonometric function to be used complex component — the part of the complex number to use for the digit extraction base — the base in which to express the numerical value digit — the digit to visualize domain size — extension of the domain in which to plot the function plot points — discretization of the real and imaginary parts
