Example 17: A stone is thrown at an angle a with the horizontal from a point in a plane whose inclination to the horizontal is β, the trajectory lying in the vertical plane containing the line of greatest slope. Show that if γ be the elevation of that point of the path that is farthest from inclined plane, then 2 tan γ = tan α + tan β.
