Coordinate Planes
... A coordinate pair tells the exact location on the coordinate plane. The x position on the X-axis goes in the x place. The y position on the Y-axis goes in the y place. *Mathematicians plot on the x-axis first. ...

Unit 9 – Roots, Radicals, and Root Functions
... Complex numbers are of the form a + bi, where a and b are real numbers. The number a is called the real part and b is called the imaginary part. If a is 0 they are called pure imaginary numbers. Add and subtract complex numbers We use the commutative, associative, and distributive properties to add ...

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.
