WebNov 29, 2024 · The Fundamental Theorem for Line Integrals allows path C to be a path in a plane or in space, not just a line segment on the x -axis. If we think of the gradient as a derivative, then this theorem relates an integral of derivative ∇f over path C to a difference of f evaluated on the boundary of C.
