So, z - h (x,y) = 0 This is an equation is a contour at g=0 for the following function: g (x,y,z) = z - f (x,y) The gradient of g points in the direction of max increase. It is also orthogonal to the contour plane. So it is the normal.
WebIn 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. A normal vector may have length one (in which case it is a unit normal vector) or its length may represent the …
