Phase Portrait Generator
This tool uses the HTML5 canvases, which your browser does not support.
Sketch the phase plane portrait of a 2D system of first order differential equations. The vector field is made up of vectors in the direction of dy/dx at individual points (x,y). Tracing a path of vectors yields a solution to the ordinary differential equation at a set of initial conditions. Initial value curves can be plotted by inputing initial (x,y) values or by clicking anywhere on the portrait.
