The normal vector, often simply called the "normal," to a surface is a vector which is perpendicular to the surface at a given point. When normals are considered on closed surfaces, the inward-pointing normal (pointing towards the interior of the surface) and outward-pointing normal are ...

Find a unit normal vector to the surface at the given point. Surface:x=\sqrt {x^{2}+y^{2 Point:(16, 30, 40) Find a unit normal vector to the surface at the given point. Surface ze^(x^2 - y^2) - 3 = 0, point (2, 2, 3). ...
The gradient vector of a function has many uses, one of which is to find a normal to a surface. Recall that for a surface {eq}g (x,y,z) = k {/eq}, where {eq}k {/eq} is some constant, then the gradient is: {eq}\displaystyle \nabla f(x,y,z) = \left...

A vector that is normal to a given surface is parallel to the gradient vector of that surface. Two parallel vectors can be considered to be the same in direction. So we need to find the gradient vector instead of finding the normal vector. Both are the same ...
