So I used to be good at math really but I’ve been out of school for ten plus years and haven’t had much use for it in my career. But every once in awhile I have thought experiments and they generally require math. I’ve looked on wikipedia and on google but am having trouble finding a kind of math cheatsheet - the kind of thing you’d find at the back of a math text book that lists all the various equations or basic concepts. I understand all the concepts so I don’t need to go and relearn everything. I just can’t remember the specific equations and so forth. I need to be able to quickly look up what (A-B)^2 equals or what the basic derivatives are, etc. Any one have a suggestion?

Okay, I’ll shamelessly promote my own site:  
[www.1728.com](http://www.1728.com)  
you’ll find it has math formulas AND calculators.

It’s great to know the formula for the volume of a sphere but it also has a calculator that will do the math for you.

Bumping this in hopes of more options.
