Algebra Editor Sample Graphics

The next three pictures show z = sin(3·r)/r, [r=sqrt(x²+y²)]

This is colored by altitude.

This is shaded by the slope of the function [direction vector (2, 1, 3)].

This is z = (x+y)/(r²+1)

This is z = cos(x²)·cos(y²)

and here is the same function in polar mode

y = cos(2·x) + sin(3·x)

x = sin(3·t), y = cos(2·t)
