Can you still figure out the volume of a cone?

If you've forgotting all the little formulas from your math-class days (and I've forgotten all but the basic ones, despite my high-level math background), this site will help you figure them out again, as well as a bunch more complicated/fancy stuff like calculating the inverse hyperbolic cotangent. Note: There is no error checking on the site. So if you're looking for the perimeter of the triangle (why you couldn't remember that equation, I don't know), you could plug in your sides as 90, 10, and 15, and it'll give you a perimeter of 115, even though that's an impossible triangle.

Very true about the error checking. As I have created WebCalc I can tell you that it is NOT error free. Although I think I make that clear on the site and provide my email address and a web based contact form to contact me. After I am contacted about a potential error I look into it right away and will have either a fix, or if I know that it really is a problem but can't fix it right away I will either take the calculator off temperarly, or make a note of it on that page.

I am working on making it the best calculator site on the net, but you can imagine the amount of time and work it requires!

Anyways thanks for the link and putting up with my rambling, and I'll try to put in error checking on that calc for you!

Considering what you're trying to build, putting in the error checking may be more trouble than it's worth. I remember having to program an interface for a bunch of those equations into my TI-81 in high school (it was part of an assignment), and taking into account all the problems with invalid data is a chore for some of those.

Regardless, great site, and good luck with it!
