De Moivre’s Theorem

In the field of complex numbers, De Moivre’s Theorem is one of the most important and useful theorems which connects complex numbers and trigonometry. Also helpful for obtaining relationships between trigonometric functions of multiple angles. DeMoivre’s Theorem is also known as “De Moivre’s Identity” and “De Moivre’s Formula”. The name of the theorem is after […]

How to Find the Perimeter of a Parallelogram

A quadrilateral has two diagonals, and four equal sides with opposite sides equal called a parallelogram. In a parallelogram its sides never intersect but its diagonal intersects each other at the center point. The diagonal divides the parallelogram into two equal parts.  A parallelogram is a two-dimensional figure, and you can calculate its perimeter using

Factoring

When solving higher degree equations, factoring is a useful tool for simplifying many algebraic expressions. Without understanding factoring, it is extremely difficult to progress in algebra beyond this point. It has been stressed in earlier chapters that terms and factors should be distinguished. Addition and subtraction of terms and multiplication of factors should be remembered.
