Question
a) Show that the distance between the parallel planes Ax + By + Cz = D1 and
Ax + By + Cz = D2 is
|D1 - D2|
d =
|Ai + Bj + Ck|
b) Find the distance between the planes 2x + 3y – z = 6 and 2x + 3y – z = 12.
c) Find an equation for the plane parallel to the plane 2x – y + 2z = -4 if the
point (3,2, –1) is equidistant from the two planes.
d) Write equations for the planes that lie parallel to and 5 units away from the
plane x – 2y + z = 3.
