Web16 de nov. de 2024 · In this section we want to revisit tangent planes only this time we’ll look at them in light of the gradient vector. In the process we will also take a look at a normal line to a surface. Let’s first recall the equation of a plane that contains the point (x0,y0,z0) ( x 0, y 0, z 0) with normal vector →n = a,b,c n → = a, b, c is given by ... Web$\begingroup$ I think this is somehow the best answer, as it stresses the fact that the derivative is defined as a linear map, i.e. the function is approximated by a hyperplane and this uniformly in the direction.Then the conclusion is clear: The directions of "zero increase" on a hyperplane are normal to the directions of steepest increase. If you relax the …
In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point.
