... frequency; however, phasors can be expressed as functions of frequency - in EE, square root of –1 is j, not i - phasors can only be used to evaluate the sum (or difference) of two or more sinusoids at the same frequency, but not their product (or quotient) - although impedances are complex numbers, ...

Inverses of Matrices
... This chapter is concerned with inverses of matrices. In a sense this is just another aspect of solving linear equations. However, since inverses of matrices are so important, we devote a separate chapter to this topic. ...

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.
