A shareware collection of six programs:
 DE.COM: graphical solutions of 2 dimensional systems of
differential equations, graphical solutions of the heat,
wave, Laplace equations in 1 and 2 dimensions, integrating
factors and graphs of power series solutions.
 CALCULUS.COM: symbolic differentiation and integration
(of simple functions), graphs of single variable functions,
parametric equations, simultaneous graphing of a function
with its first and second derivatives, and surface contour
of z=f(x,y).
 ODE.EXE: an update of the author's previous program "EULER.EXE".
It allows the user to choose between RungeKutta method
and Euler's Method to get the solutions of systems of ode's.
 EULER3D.EXE is a test program for 3dim extension of ODE.EXE.
 STRING.EXE: animation of the vibrating string.
 LP.EXE uses 3dim graphics window to show graphical meaning
of simplex method for linear programming.
