Halley took a paper written by De Moivre to the Royal Society. Through this introduction De Moivre became part of the exclusive society where men like Newton, Halley, Wallis and Cotes exchanged and clashed over ideas that were to become the many of the founding precepts of mathematical theory today.

Proof: To establish the ``basis'' of our mathematical induction proof, we may simply observe that De Moivre's theorem is trivially true for $ n=1$ . Now assume that

In general, use the values . These are the cube roots of 1. Applications of De Moivre’s Theorem: This is a fundamental theorem and has various applications. Here we will discuss few of these which are important from the examination point of view. The n th Root of Unity: Let x be the n th root of unity .
