To graph an equation, enter an expression into the expression box and press **Enter**. Grapher will automatically figure out what equation you're attempting to graph.

You can also pan around in the coordinate plane by clicking and dragging your cursor inside of it.

You may use the following constants anywhere in your equation:

- pi
- e

Graph supports both Cartesian (x, y) and Polar (r, θ) graphs.

You may use either by selecting the unknown variable from the dropdown menu, next to any equation.

You may use the following functions anywhere in your equation

- abs() // abs(-1) = 1
- round() // round(3.5) = 4
- ceil() // ceil(3.1) = 4
- floor() // floor(3.9) = 3

- pow() // pow(3, 2) = 9
- root() // root(9, 2) = 3

- log() // log(100) = 2
- ln() // ln(e) = 1

- sin() // sin(pi/6) = 0.5
- cos() // cos(pi) = -1
- tan() // tan(pi/4) = 1
