Where Can I Find a Math Search Engine or Equation Identification Tool?

[ognik]

Is there a maths search engine? If not, I wish there was...

Does anyone know any good way to search for maths expressions online, be it in Latex/mathtype or text?

Are there, alternatively, websites where you can at least get some form of identification of an equation so that you can use those terms to search on? (Ex: the solution to an integral eqtn turns out to be a Beta function; I would have liked to input the eqtn somewhere and have it identify that I should look at beta functions for it's solution)

It is annoying that there isn't a "maths search engine" as you say, but most of the time if you type an equation or some information about it into Google, it gets the idea and gives you what you want :)

Not that consistently I find, and often many results but none close enough to be useful...

Incidentally, is there a .tex viewer - often I get a bunch of .tex files; I have winedt but would prefer to just quick-view rather than open in winedt...
