It's the distance along the normal to the plane, x+2y+z=4.

Do you know how to find a vector normal to that plane? - Oct 13th 2011, 06:43 PMesander4Re: Shortest distance from point to plane
Is it the cross product of the partial derivative of x and partial derivative of y? And then the magnitude of that?
