Potentials


Let F be a vector field in a domain D. Then the line integral [Equation goes here - download the original pdf to see it.] is independent of path, if, and only if [Equation goes here - download the original pdf to see it.] for some scalar field f. [Example goes here - download the original pdf to see it.]
