Hello, I am trying to solve for the surface area of a odd surface for a fire relief PSV and needed to do a line integral but I was reading into my calculus book and going back to the definition of arc length I am confused:(adsbygoogle = window.adsbygoogle || []).push({});

L = lim[tex]_{n\rightarrow\infty}\sum (P_{i-1}*P_{i})[/tex]

Multiplication should give you an area like when you multipy the function of a curve C by the length just like an integral. This is a fundamental definition so I can not go back any farther maybe im just missing something logically in my own mind. Understanding line integration is also fundamental to fluid dynamics and E&M which are both of great interest to me.
