I want to check my understanding of the line integral:(adsbygoogle = window.adsbygoogle || []).push({});

For a scalar line integral, what we have geometrically is

the area between a curve a given function, yes? Hence,

it can be thought of as a kind of thin wall, correct? And

where our function is f(x,y)=1, we have the length of the

curve we are integrating over.

For a vector line integral, we actually sum of the unit tangent

vectors along some curve, right?

Thanks in advance.
