Equation Grapher | gCalcD

Welcome to the gCalcD Equation Grapher, the only online equation grapher that graphs any well-defined equation (and level curves) in Cartesian and polar coordinate systems, and it's free!

Equation grapher for graphing equations in the general form g(x,y) = f(x,y) in the Cartesian and Polar coordinate systems.
To graph equations in the form y = f(x) use the faster Function Grapher.

To use the equation grapher select Cartesian (default) or Polar Coordinate System.

To graph an equation type in its expression and press Draw Graph (or press Enter on the keyboard). Syntax

To graph two or more equations on the same coordinate plane first press Draw Multiple Graphs...Quick Start

Note: This Equation Grapher graphs any well-defined equation in x and y (or in θ and r). If an equation is in the form y = f(x) (or r = f(θ)), use the Function Grapher instead. It graphs functions almost instantly and it's more accurate in graphing functions.


To use this sophisticated, easy-to-use online equation graphing calculator you need to download Java from Java.com, it's free. Below are images of Equation Grapher (Online Equation Graphing Calculator). Already have Java? Trouble-shooting

π: Ctrl+P or Alt+P or pi.
: Ctrl+8 or Alt+8 or infinity.
θ: Ctrl+T or Alt+T or theta. You can also use x or t instead of θ in polar mode; they will be replaced by θ when you press Draw Graph or Enter on the keyboard.

Using your mouse: change the scales and labelsNew, translate the origin and rotate the axes

Example - Equations:

x = 3y^2-4y-2  parabola

x^2-3xy-2y^2+4x+2y-2 = 0  hyperbola

sin(2x) = sin(2y)  Graph it!

sin(x) = sin(xy)  Graph it!
