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: Rectanglar equation: 1. Y = a x^2 + b x + c. 2. Y = log Parametric equation: x = a sin; Y = b cos Polar equation: r = a cos
