Covers the multiplication and division of complex numbers given in exponential and their equivalent formulas in polar form (deduced from the exponential ones) as an introduction to the deduction of De Moivre's Formula and its use to find complex roots.

Introduces the exponential form of a complex number with a brief mention to power series so students can understand the importance of the angle being in radians.

Example of a word problem involving fractions - how to interpret it and apply algorithms to solve it.

Example of getting the polar form of a complex number if the cartesian form is known(number placed in the fourth quadrant).

Part 3: Shows how to solve absolute value inequalities, example abs(2x-1)<5

Part 2: Shows how to solve absolute value inequalities, example abs(1-2x)>-3

Part 1: Explains how to solve simple equalities/inequalities of the type abs(x)=constant, abs(x) < constant, abs(c) > constant.

This video reviews the variables involved in both forms of a complex numbers and deduces how to get the modulus and the angle when given a complex number in Cartesian form.

Explains how to rewrite a cubic polynomial as the product of a linear term and a quadratic, by dividing the cubic by the linear term.

This recording looks at how to identify the nature of the region in the complex plane that satisfies |z-z0|=r. This is then illustrated further with a specific example.
