Hi,

I'm a octave newbie and try to work with differential and integral
calculus. I need some help to get a working example for this. Could you
help me?

Here is a simple example:

f(x)=x^3+-2x^2+5
f'(x)=3x^2-4x

and for example integrating f'(x) to see that f(x) results.

And what is with more difficult calculations? I know only the german
names, so perhaps I do a wrong translation. What is with chain rule
(Kettenregel), quotient rule (Quotientenregel) or all the other funny
things to do differential or integral calculus. Could octave detect
which rule to use for which function or have I to tell octave the right
rule? Can octave do a differential calculus for this?

f(x)=(x^2-3x)*sin x
f'(x)=?

I hope someone could help me with this questions. Some friends are
working with matlab or maple and told me this is working with this apps.
So I hope it works also with octave.

regards
Andreas
