ODEcalc (tm) - Version 2.10 ODEcalc v. 2.10 for Windows 3.x/95/98: An Ordinary Differential Equation (ODE) Calculator! State your equation and boundary or initial value conditions and it solves your problem. Plots solution, y, and derivative, ydot, versus x. Solves most Boundary Value Problems (BVP) & Initial Value Problems (IVP) for Nth order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it's short! Great teaching tool! Helps students understand difference in BVP & IVP and their importance in solving practical ODEs. ODE and algebraic system of equations may be solved using the methodology in this demo. Changes: Windows 95/98 capability added. ODE210.zip has replaced ODE203c.zip
