Several Species of Small Furry Mathematical Equations Gathered Together in a Cave and Grooving in C++

I need testers for this program, so if you have the time, it would be greatly appreciated.

Introduction:

First off, hello, my name is Peter Mullen. Thank you for supporting this small project of mine. I'm doing this in my own spare time simply because I want to practise programming by making something practical that I and others can use to make their life (and homework) a little easier.

What I need you to do:

Currently the program is very buggy. I need you to test this program, see if the equations give correct answers, see if it spasms out or crashes, and email your results to: error-report@platinum-productions.org

If you dont do this, the program won't get fixed because I won't know what to fix, so it would be greatly appreciated if you could send any problems to me.

So, what is it?:

Basically this is a small enough program written in C++ to solve maths problems that need formulas to solve. It has the basic formulas included in the standard State Examinations Commision formula/table book for the Leaving Certificate and Junior Certificate maths courses. There's nothing fancy to it, it's a command window program, no fancy GUIs (yet). It's lacking some formulas, I know, but I'm working on adding more and more. To date, it has the formulas for:

Length and area
Surface area and volume
Co-ordinate geometry (missing some)

Why did I make it?:

I was bored. That's basically it. I wanted to practise programming, but I also had co-ordinate geometry homework, so I made a program that does the homework for me. Two birds with one stone for the win. After that, I just kept adding formulas to it.
