The line integral of a vector function F = P i + Q j + R k is said to be path independent, if and only if P, Q and R are continuous in a domain D, and if there exists some scalar function u = u (x, y, z) in D such that. If this is the case, then the line integral of F along the curve C from A to B is given by the formula.
