Heya!(adsbygoogle = window.adsbygoogle || []).push({});

I was hoping someone could clear this up for me: how would a line integral be represted graphically? I've always liked calculus because it's easy to visualize (almost all the problems have graphs associated with them) - but I don't quite get how to visualize a line integral. Or is it a concept that can't be easily visualized?

any help would, well.. help.

I've also been pondering something my teacher brought up last week:

Let's say the line integral of f(x,y,z) over a curve C is equal to zero, then would it have to be true that f(x,y,z) = 0 on C?

Thank you! I eagerly await a response.
