Is there any kind of software that will allow me to input my equations and create a visual display?

Math software? For me, these are the best options:

*** Texas Instruments' Derive ***

Currently at version 6, its very intuitive and has a command-line style. Can graph *simple* 2D and 3D equations on the fly but more complex problems can be hard to input. Great for high schools students.

It handles a more advanced math too, like number theory, non-trivial integration, matrix algebra, graph theory.

Can be expanded with "modules" (you can add your own functions and algorithms).

Belive me, it's so easy to use that I replaced my Windows calculator by this program

*** Maplesoft's Maple ***

I think it's currently in version 10, but I don't know much about this one. The symbolic manipulation is very easy and has a symbol recognition feature. Creates amazing interactive reports and sheets.

Try a demo and see if it serves your needs.

*** Matlab ***

This one is a must have if you work with science/research/I&D in general - allows integration with popular hardware and other products. You can develop a mathematical model for any problem and simulate it. From GUI's to repetitive calculations, gathering data, statistics... everything can be programmed and simulated. But mastering this software takes a while.

*** Wolfram's Mathematica (/*bows*/) ***

This one I personnaly recommend if you have:

- the money to buy it **

- the time to master it.

You can do, basically, everything - primitives, derivative, matrices, graphic representations, create and design math presentations (called "notebooks"), *-algebras, graphs, strings, programming, number theory, combinatorics, numerical computation, diferential equations, 2d-3d graphs of anything - from random data to complex zeta functions, dynamical systems, differential geometry - you name it.

..Every day you find a new command or feature. It's just amazing.

But in the beginning it can be REALLY hard to interact with the program. So be prepared if you are choosing this one.
