2D Phase Plane Plotter by Marek Rychlik

Enter your system of differential equations dx/dt = f(t,x,y) and dy/dt = g(t,x,y).

You may plot the following using the down arrows along the edges of the graph:
y vs. x (Phase plot)
x vs. t
y vs. t
The scale used will be determined by the variables selected with the down arrows.
For example, if you have y vs. t selected, the scale for the other dependent variable will be incorrect unless the Max and Min values are equal for each variable.

Examples of valid expressions:

0.5*exp(y) 5*sin(t) y^2*sin(y) ln(3*x) abs(t^2-y) sin(PI*y) step(t) sqrt(y)
