VisualMethodos is a software for Windows 3.x which requires BWCC.DLL,included
in the zip file. 

VisualMethodos is a mathematical education software which works with 
Numerical Methods.

It solves Differential Equations, Numerical Integration (showing the area 
calculated if you want to),Polynomial Interpolation (using a function or 
mouse clicks to provide the data points), Approximation (it choses what 
function the data points most look like, or it can approximate (fit) them 
to a straight line (a+b*x), a rational (1/(a+b*x)), a parabola (a+b*x+c*x^2),
a power (a*x^b) or an exponential function (a*b^x) ).
     
It can work with two functions if it's need to compare them, displaying their 
graphs side by side, and showing the input data points if you want to.

When a graph function is displayed, one can drag the points to recalculate 
them and graph the function automatically.

One can also copy a graph function displayed to the clipboard.
     
Its Help is easy and complete, and, in the full release, its error messages 
are spoken (if it can detect a sound card)
