WebSep 3, 2024 · Your gradient looks correct to me. Use the chain rule. Along the level curve f ( x, y) = c, as long as ∂ f ∂ y ≠ 0, we can consider y as implicitly a function of x. Then ∂ f ∂ x + ∂ f ∂ y d y d x = 0 so d y d x = − ∂ f / ∂ x ∂ f / ∂ y Share Cite Follow answered Sep 2, 2024 at 19:33 Matthew Leingang 24.5k 1 35 58 Add a comment WebFind the elevation and coordinates of any location on the Topographic Map.
