Parametric Grapher
Plot parametric curves x(t), y(t) over an adjustable parameter interval — circles, ellipses, Lissajous figures and cycloids.
Plot parametric curves x(t), y(t) over an adjustable parameter interval — circles, ellipses, Lissajous figures and cycloids.
The parameter is t (radians for trigonometric functions). Both axes use the same scale.
Plots a curve whose coordinates are both functions of a parameter t: the point traces the curve as t runs over an interval. Parametric form describes curves that are not graphs of functions — circles, loops, cycloids and Lissajous figures.
Both axes use the same scale so that circles look round, and the starting point is marked so you can see the direction of travel.
Example
x = cos(3t), y = sin(2t), t ∈ [0, 2π]
