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
