FirstOrderSolve

A Maple package for computing local and algebraic solutions of first order autonomous AODEs

This Maple package computes power series, Puiseux series and algebraic solutions of first order autonomous ordinary differential equations where the unknown function and its derivative fulfill a polynomial equation. The standard commands of Maple might not find these solutions and ...
