Nettet16. nov. 2024 · 1. Summary A line integral is an integral of a function along a curve in space. We usually represent the curve by a parametric equation, e.g. r ( t) = [ x ( t), y ( t), z ( t)] = x ( t) i + y ( t) j + z ( t) k. So, in general the curve will be a vector function, and the function we want to integrate will also be a vector function.
