With MathGrapher, you can visualize function equations, parametric equations, and/or polar equations. You can also animate an equation by defining the range of one or more parameters: a, b, c, or d.

Here are some examples:

Function equation:
1.
y = a*x^2 + b*x + c

2.
y = log(2,x)

Parametric equation:
x = a*sin(t); y = b*cos(t)

Polar equation:
r = a*cos(b*t + pi/2)

You can select equations from the equation gallery that contains some predefined equations.

You can save the equations for later use.
