Parametric Curve Grapher

Plot parametric curves defined by x(t) and y(t) and download the graph as PNG.

What Is the Parametric Curve Grapher?

A parametric curve is defined by two functions of a parameter t. This plotter lets you visualize shapes like circles (cos(t), sin(t)), spirals, and Lissajous figures that cannot be expressed as y = f(x).

Formula

x = x(t), y = y(t)

How to Use

Enter x(t) and y(t) expressions using t as the parameter. Set the t range (start and end values). Click Plot to render the curve. Download the result as PNG.

Example Calculation

To plot a circle: set x(t) = cos(t) and y(t) = sin(t) with t from 0 to 6.28. To plot a Lissajous: x(t) = sin(3t), y(t) = sin(4t) from 0 to 6.28.

Frequently Asked Questions

What is a parametric curve?

A parametric curve uses a third variable t (the parameter) to define both x and y coordinates, allowing you to trace curves that double back on themselves.

Can I plot a helix?

For 2D, yes use x(t)=t*cos(t) and y(t)=t*sin(t) to get a spiral.

What t range should I use?

For trigonometric functions, 0 to 6.283 (2π) is typical. For spirals try 0 to 20.
