PhaPl: Phase Plane Helper. PhaPl is a software to research and plot phase portraits of autonomous systems of 2 differential equations on a plane. PhaPl works as a site or as a local html-page that works offline. Go to task input/choice below. Download archive for local offline use (~9 MB to download, ~37 MB to be stored unpacked on disk).
Phase plane. Author: Pablo Rodríguez-Sánchez. Topic: Differential Equation. Phase spaces are used to analyze autonomous differential equations. The two dimensional case is specially relevant, because it is simple enough to give us lots of information just by plotting it. Text below.
dfield (direction field) and pplane (phase plane) are software programs for the interactive analysis of ordinary differential equations (ODE). The software is described in detail in the manual Ordinary Differential Equations using MATLAB.
Theorem 1 (Identical trajectories) Assume that Picard's existence-uniqueness theorem applies to initial value problems in D for the planar system (1). Let (x1(t); y1(t)) and (x2(t); y2(t)) be two trajectories of system (1). If times t1, t2 exist such that. (3) x1(t1) = x2(t2); y1(t1) = y2(t2);
