Grapher
An editor window to test your algebraic functions,
gives a graphical output on the range of -1 to 1.
You can use C# operators such as: + - / * % etc.
Comment out something with /* */
Mathematical functions you can use:
abs acos asin atan asin ceil cos exp floor log log10 max min pow round sign sin sqrt tan trunc clamp clamp01

Does it do reciprocals?
You mean hyperbola? Like N/x where N is a constant?
It does:
Really an interesting work, congratulation! 
Thanks. It uses the C# compiler under the hood, so the coding was easy, it was done in a few hours. I tested it and it works on mac os x so it must work on pc’s as well.
I’m impressed. How about differentiation?
Can you give me an example? I’m not into math that much
Technically it should be able to evaluate any function that contains the supported operations while the result is within the range of -1 to 1.
