Link no worky...but assuming it does, where the hell was this when I *needed* it back in undergrad math/stats classes...?! :-)

Neat. But it would be cooler (and more useful for the school crowd) if it had the proofs too.

O fer chrissake. How to find the perimeter of a triangle, given the lengths of the sides? You've got to be kidding.

You're right gleuschk, that is a little facile. I found this one to be a bit of a no-brainer as well.

Too bad it doesn't check for validity. I did the above triangle calculation with lengths 1, 1 and 100. Sure enough, it gave be a perimeter of 102. It also accepts non-positive lengths.

But overall, quite handy if you already have some mathmatical sense.

Much more interesting to me is tools like the Fair Division calculator which you can use to fairly divide rent or pies among a number of people.

Quick Math. Used in combination with SOS Math were a pair I found useful in school..
