ODEcalc

An Ordinary Differential Equation (ODE) Calculator! State your equation with boundary or initial value conditions and ODEcalc will solve your problem. Plots solution (y) and derivative (ydot) versus x. Solves most Boundary Value Problems (BVP) & Initial Value Problems (IVP) for any order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it's short! ODEcalc helps one understand difference in BVP & IVP and their importance in solving practical differential equations. PDEs, ODEs and algebraic system of equations may be solved using the methodology in this demo. Great for learning BVP & IVP solution techniques. Solvers used are based on Automatic Differential (AD) and Operator Overload techniques.
