What does line integral really mean, what is it doing?(adsbygoogle = window.adsbygoogle || []).push({});

Say you have a function f(x,y,z) and you integrate it w.r.t. arc length along some curve C.

Is this like finding the area under C over f? Like if you are walking along C, and the vertical area covered below you is the integral?

It's hard to say what I mean, but is this correct?

Cheers,
