In each of the following cases, determine the direction cosines of the normal to the plane and the distance from the origin.

z = 2

The eq. of the plane

z = 2

Direction ratio of the normal (0,0,1)

This is the form of

lx + my + nz = d (∴ d = Distance of the normal from the origin.)

Direction cosines = 0,0,1

Distance(d) = 2
