[Part 2]
... (If M2 = I5 i . e . , there is only one cell in the second group, then it cannot exchange with both A* and AA. The rearrangements corresponding to this case are eliminated in (6) since it occurs when !q = k2 = 1 and G(-l) = 0.) The remainder of the proof follows the same procedure. Define k. = 1 i+1 ...

Subtracting Fractions with the same Denominator
... To add two fractions with the same denominator, add the numerators and place that sum over the common denominator. Subtracting Fractions with the same Denominator Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator. numerator denomina ...

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.
