IOTD: Watcheq: What Equation

Watcheq: What Equation, by Maikol

Some time ago I realized I had no program that could represent quickly a one-variable function. I did not want to learn mathlab, just wanted to see its behavior and no more. So I did this!

It can represent any number of functions, each one with different colour. No matter what expression is given, you'll watch it. However do not know if I'll finish it soon... exams are coming!

At this picture there are a Gaussian and Rayleigh functions, hiperbolic tangent and a few others.

Not bad, though I would recooemd you to have a look at gnuplot.

There's also an old Windows program I used to use for this called Graphmatica. Perfect for small things like this. - miran

sharp looking.
This can't do complex funcs like yours, but good for visualization:

There's also f(x) viewer [sixdots.de], which does almost the same. - ADmiral
