A. Cherepanov

Abstract


The article describes PhaPl, which is a web application to plot and research phase portraits of autonomous systems of two differential equations. PhaPl uses SymPy library for symbolic computation and PyPy.js to run SymPy in a web browser allowing online and offline modes of work. The article describes results the user can get without programming and without conffguration. The software has been deployed in Plekhanov Russian University of Economics since 2018 for teaching purposes.
