+Euler's Formula, $e^{ix} = \cos x + i \sin x$, beautifully links the [Exponential Function](/wiki/exponential_function) with [Trigonometry](/wiki/trigonometry) through the imaginary unit. It stands as a profound statement of mathematical unity, revealing deep connections between seemingly distinct fields. This elegant identity is essential in many areas of science and engineering.
