Grapher Instructions

Usage

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.

Constants

You may use the following constants anywhere in your equation:

• pi
• e

Variables

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.

Functions

You may use the following functions anywhere in your equation

General

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

Exponents

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

Logarithms

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

Trigonometry

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