Parametric Curve Grapher | gCalcD

Welcome to the most powerful Online 2D Parametric Equation Grapher. Graph, differentiate. Sophisticated, easy to use, and it's free!.

Online Parametric grapher for graphing parametric curves, p(t) = (x(t), y(t)), in the Cartesian and Polar coordinate systems.

■ To use this parametric grapher select Cartesian (default) or Polar Coordinate System.

■ To graph a parametric curve type in its expression and press Draw Graph (or press Enter on the ketboard). Syntax

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

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 - Parametric Equations of 2D Curves:

p(t) = (4sin(t), 3cos(t))  ellipse (Cartesian)

p(t) = (2tcos(t^2),3t^2) domain=(-1,1)  Graph it! (Polar)

p(t) = (4cos(3t),5sin(9t))  Graph it! (Polar)
