attached is a file called Derivative.py.

It computes derivatives and is based on an algorithm found in 
Numerical Recipes in C.

What to do you think about it and has anyone started a "serious" 
calculus oriented subpackage for Numerical Python in general?

I mean: derivatives, partial derivatives, jacobian, hessian 
implemented fast and precise.

On another note, why isn't infinity defined in NumPy?

Why is tan(pi/2) a number even if big? Shouldn't it be infinity?
