3 days ago Web 8. Find the equation of a plane which is at a distance 3√3 units from origin and the normal to which is equally inclined to coordinate axis. Solution: As the normal to the plane is equally inclined to the axes we have, cos α = cos β = cos γ. So, cos 2 α + cos 2 α + cos 2 α = 1. 3 cos 2 α = 1 ⇒ cos α = ± 1/√3.
