Relplot constructs high-resolution PostScript or PDF plots of the solutions to equations on two variables. Unlike most other plotters, it can handle general equations and inequations, not just functions, and it can plot multiple equations at once and their logical combinations. For more information, see the FAQ.
Some interesting equations to try:
x^2 * y^2 = 1 x^y = y^x (r-1/2)^5 = 4yx^3 - 4xy^3 ((xy(x-y)(x+y)(x^2+y^2-4))^2 - 1) < 1 ln r = sin 4x^2 + cos 5y^2 + x/4 y = 3x sinc(pi^2 / r) y>|x| & y<sqrt(exp x + exp -x - 2) x^2 <= floor|ay|, x^2>|ay| where a=sqrt(5) 0 = (x^2+(y-(x^2)^(1/3))^2) mod 1 d = 30+sin 90th, d=20, d<10 where d = x^4+y^4 (x mod -y)*(1/y mod .2)=0 && y<0 (5x mod 1=0 || 5y mod 1=0) & r<2 u<sin^2 2v,|r|>2 where u=x+y, v=x-y f(x-1)mod 1=0,f(4)=4x where f(n)=(r+cos(10th))^2-n
