While we're talking about handy computer programs, I was hoping to find
a little program that would allow animations of y = Acos(kx-wt+phi).
Ideally the variables could be easily adjusted, say with a little
slider. I wanted set it up in a computer lab so the students could
cantrol the parameters and get immediate feedback on how they affect
the wave.
A well done spreadsheet with macros could do the job, but I don't have
the time to fuss with learning macro programming. Macs come with a
graphing calculator, but the only parameter has to be called "n", which
isn't very useful here. I searched the web without great luck. The
other choice is to by a site license for Mathematica or MathCAD or some
such, but that is rather expensive for one little demo.
So, anyway, does anyone know a cheap, intuitive, foolproof application
to animate y = Acos(kx-wt+phi)?
