Factoring Polynomials a=1
... Math 103 - Beginning Algebra II Section 5.6 Factoring polynomials in the form x2 + bx + c Introduction Factoring expressions of the form x2 + bx + c is the reverse process of multiplying two binomials of the form (x + m)(x + n). For example, we know that (x + 5)(x - 3) = x2 + 2x -15. So x2 + 2x -15 ...

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.
