+**Euler's Formula** is a profound mathematical identity connecting [complex exponentials](/wiki/Complex_Exponentials) with [trigonometric functions](/wiki/Trigonometric_Functions). Expressed as $e^{ix} = \cos x + i \sin x$, it elegantly unifies fundamental mathematical concepts, revealing a deep symmetry within numbers.
