欧拉恒等式 Euler's identity

（重定向自Euler identity）
Fórmula de Euler para un ángulo general.
The exponential function ez can be defined as the limit of (1 + z/N)N, as N approaches infinity, and thus eiπ is the limit of (1 +iπ/N)N. In this animation N takes various increasing values from 1 to 100. The computation of (1 + iπ/N)N is displayed as the combined effect of N repeated multiplications in the complex plane, with the final point being the actual value of (1 +iπ/N)N. It can be seen that as N gets larger (1 +iπ/N)N approaches a limit of −1.

欧拉恒等式是指下列的关系式：

e^{i \pi}+1=0\,

其中e\,是自然指数的底，i \,是虚数单位，\pi \,是圆周率。

这条恒等式第一次出现于1748年莱昂哈德·欧拉在洛桑出版的书Introductio \,。这是复分析的欧拉公式的特殊情况。

理乍得·费曼称这恒等式为「数学最奇妙的公式」，因为它把5个最基本的数学常数简洁地连系起来。
