My english is not good, but i want to say that this code is very good. I like idea of this author, but this code is not very fast. My own similar code is faster three times more than it. Although, my code is not fastest. ;)
Best regards.

Great Job
I was thinking about giving option of adding new functions as plug-ins (dll?)
That would make it cooler.
And I would love to see an explanation of the code.

Habe es in mein Programm (VC++5.0) eingebaut.
Stelle fest: am genauesten rechnet
1. Mittelpunktsregel
2. Integration mit Trapezregel
3. Simpson ( hier Abweichungen von 1) bis zu 10 %.
Beispiel: sin(x)/x ( f�r x= 0 bis x = 3)
nur 1) berechnet richtig, 2) und 3) keine Berechnung m�glich.

Warum ?

how am i to verify the results?Maybe the code should be
modified to ask another f(x) at the end so the window wouldn't close and the user can test another function.
You could just put in a prompt ,say 'Quit Y?N ?'..
Otherwise good ,i've gotto see the code..

Thanks for this great piece of code.

template <class T>
class CSqrt1Function : public CFunction<T>
{
...
virtual CFunction<T>* GetDerivate() const   {return new CDivL0Function<T>(1/2, new CSqrt1Function<T>);};
};
