Talk:Line integral

A line integral is the area under a function along a specified curve.

I have to admit that I have great difficulties to align this description with the usual definition of a line integral, i.e., something like

$\int _{\mathbf {C} }\langle {\vec {f}}({\vec {s}}),d{\vec {s}}\rangle$

(I used this notation to stress the scalar product)
