Proof of Why Gradient of a Function is Perpendicular to its Level Curves

Описание к видео Proof of Why Gradient of a Function is Perpendicular to its Level Curves

In this video, I take the familiar multivariable/vector calculus idea that the gradient of a 3D function is orthogonal to its level curves, prove this idea, and then try to extend the proof to higher dimensions of space.
