Hello everyone, at 1:26:58 I mentioned the rho-phi method but I made a mistake in the naming convention. The proper term for this type of method is the spherical coordinate system (not a polar coordinate system) and it involves three values: rho, phi and theta. Theta is the angle measured from the known x or y-axis (either 100 or 010) along the primitive circle. While phi is measured from the z-axis (001) along a vertical plane. Rho is the distance from the center of the sphere to the intersection at the surface which is basically just the radius of the sphere, in this case. We will still arrive at the same answer as shown in the video but this is the conventional way to this.
