Title :
Establishing a "Pythagorean" Result [Letter to the Editor]
Abstract :
A request was made in an earlier letter [1] for help in proving some trigonometric results arising in antenna theory. It is the purpose of this letter to show just how such results might indeed be established. Perhaps the most instructive way to establish them is to do so from first principles, using mathematics that might be familiar to graduates in mathematics or engineering.
