I took a look at the line_integrate() function. The Curve class is something of a start. Though, I like very much Raoul's idea for a single class to represent everything (path/surface/volume). I think this is doable. But,
> would then represent an integral over an N-dimensional hypervolume I have not had a relevant course that would acquaint me with 'N-dimensional hypervolumes'. Nevertheless, I am willing to read up on it. I hope that just implementing integrals in such hypervolumes wouldn't be too different from the 2 or 3 dimensional case. > How are they numerical in nature? Integrals are by their nature symbolic.

I said numeric from the user's perspective. For example, if a user wants to calculate a line integral, say, then unlike integration in one variable where we could do indefinite integrals and expect the answer to be in terms of elementary functions, here, we might be just concerned with the numeric result of the integration. Of course, giving the output in terms of elementary functions would be much better but I am inclined to think that we will probably need rely heavily on some kind of a numeric backend. -- You received this message because you are subscribed to the Google Groups "sympy" group.
