Tonight I had the need to plot some simple equations, like: y = 1.2x. This gave me the perfect opportunity to dig around for a web app to do the plotting, rather than simply sketching out a few points on paper.
A bit of poking around found: Fooplot.com. It's nothing particularly special, though it does appear to do the Right Thing most of the time.
The one cool part is that you can throw equations at the end of a URL and have them plotted, something like:
I'm sure there are sexier options out there, but for now, fooplot seems like it'll do the trick.
Frankly, I'm not sure if Mrs. Buck (my high school math teacher) would be impressed that I'm plotting stuff, or depressed that I need a program to tell me what y = 1.2^x versus y = 2^x actually look like.
