Is there a site to search for formulas? I often come up with formulas that I would like to know the name, where they are used or what they are related to. One would type, for example, $\sin(a)\cos(b)+\sin(b)\cos(a)$ and it would intelligently associate it with the sum of sines formula. I know this would be no trivial service but I find it would be a great tool.
Searching for formulas?

0There are many lists of formulae on the internet, but if you want something which will parse what you write then you want a computer algebra system – 2012-03-15
