Abraham de Moivre
The life of Abraham de Moivre - Calculated His Own Death.
De Moivre's Formula
A fundamental bridge between complex numbers and trigonometry.
\[ (\cos x + i\sin x)^n = \cos(nx) + i\sin(nx) \]
Normal Approximation to Binomial
De Moivre was the first to discover the normal curve as an approximation to the binomial distribution.
\[ P\left( \frac{S_n - np}{\sqrt{np(1-p)}} \le x \right) \approx \Phi(x) \]
