... The terms of the expression are separated by addition. There are 3 terms in this example and they are 5x 2 , x , 7 . The coefficient of a variable term is the real number factor. The first term has coefficient of 5. The second term has an unwritten coefficient of 1. The last term , -7, is called a ...

... d) Absolute Value of a number is the number’s DISTANCE from 0 on the number line. It is always 0 or POSITIVE. |x| is the absolute value of x. If x> 0 then the absolute value of x is x If x < 0 then the absolute value of x is –x which brings us to opposite numbers. ______________________________ e) O ...

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.
