RE: New algorithms for numerical integration and ODE solutions
Dan,

I have coded the approximation for the derivative to be:

f'(x) = (f(x+h) - f(x)) / h

And not the more accurate form:

f'(x) = (f(x+h) - f(x - h)) / 2h

To avoid the case when f(x+h)=f(x-h) around x=0, which would lead to an error-geneating zero slope.
