# Plotting & Graphics

Plotting and graphing are methods of visualizing the behavior of mathematical functions. Use Wolfram|Alpha to generate plots of functions, equations and inequalities in one, two and three dimensions. Gain additional perspective by studying polar plots, parametric plots, contour plots, region plots and many other types of visualizations of the functions and equations of interest to you.

Graph a function of one variable as a curve in the plane.

#### Plot a function of one variable:

#### Specify an explicit range for the variable:

#### Plot a real‐valued function:

#### Plot a special function:

#### Plot several functions:

#### Plot a function on a logarithmic scale:

#### Plot on a log-linear scale:

Plot the solution set of an equation in two or three variables.

#### Plot the solution to an equation in two variables:

#### Plot a quadric surface:

Graph parametric equations in two or three dimensions.

#### Draw a parametric plot:

#### Specify a range for the parameter:
