The Angular Normal of a Plane are the Polar and Equitorial Angles that the Normal to the Plane from Origin makes with the Positive Direction of Polar and Equitorial Axes.
Angular Normal of a Plane is calculated using the following steps
Find the Coordinates of Point Projection of the Origin on the Plane. For a Plane given by equation \(Ax + By + Cz + D=0\) the Coordinates are given as
\((\frac{-DA}{A^2+B^2+C^2},\frac{-DB}{A^2+B^2+C^2},\frac{-DC}{A^2+B^2+C^2})\).
Calculate the Polar and Equaitorial Angles sutained by the Coordinates of Point Projection of the Origin on Plane using the Angle Measurement Formula.
