I have encountered this equation:
##\cos^2 \gamma = \cos^2 \alpha \cdot \cos^2 \beta##
According to the paper, this is a trigonometric identity, but this is the first time I have encountered this. The angles ##\alpha## and ##\beta## are somewhat similar to the components of the distance formula, and ##\gamma## is the resultant distance.
