Orthogonality of level curves and the gradient vector

Видео

We demonstrate that level curve tangent vectors are always orthogonal (perpendicular) to the gradient vector at every point on a surface where these vectors exist and are non zero. We perform a proof of this fact and then illustrate with a si..., видео от 2023-09-21 загрузил на rutube Мастерство и Стремление...
