This theorem has a powerful converse:

WebWhen we proved the gradient of a function is orthogonal to the level sets of the function for some constant , my professor was quite explicit in stating that the implicit function theorem (IFT) is needed for the proof without giving a clear reason why.
Web7 years ago So, when you show us the vector field of Nabla (f (x,y)) = , you say that the more red the vector is, the greater is its length. However, I noticed that the most red vectors are those in the center (those that should be less red, because closer to the center, smaller the variables) • ( 56 votes) Upvote Flag Dino Rendulić
