... two graphs are reflections of each other about the horizontal axis. This is because by graphing the opposite of h(x), each point in the positive part of the range of h(x) becomes negative, and each point in the negative part of the range of h(x) becomes positive. Since zero has no opposite, h(x) = 0 ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
