In the following cases, find the coordinates of the foot of the perpendicular drawn from the origin.
3y + 4z – 6 = 0
Let the coordinate of the foot of ⊥ P from the origin to the given plane be P(x,y,z).
x + y + z = 1
Direction ratio (1,1,1)
This is the form of
lx + my + nz = d (∴ d = Distance of the normal from the origin.)
