DeMoivre’s Theorem: A Mathematical Gift That Keeps on Giving

DeMoivre’s Theorem (written above) is a simple theorem relating complex numbers to trigonometry. It was proposed and proved for all positive integers n by Abraham DeMoivre (1667–1754), a French mathematician who was a religious exile in England from a young age and a friend of ...

Finalé of Trigonometric Limits and the Squeeze Theorem: An Introduction to Calculus

This additional side is equivalent to tangent of theta. Why? If we call this side say, Side C, tangent is defined as being the opposing side divided by the ajacent side, so tangent theta must be equal to Side C divided by the ajacent side, which in this case is just 1. ...

Trigonometric Limits Part 1: An Introduction to Calculus

It’s a helpful way to visualize basic trigonometric functions. For the rest of this guide, we will be using radian notation, instead of the standard degree one you may be familiar with. As a reminder, any degree can be expressed in terms of a radian, with the core ratio being that 180 de...
