+Euler's Formula, $e^{ix} = \cos x + i \sin x$, is a cornerstone of mathematics, weaving together the exponential function with [Complex Numbers](/wiki/complex_numbers) and [Trigonometry](/wiki/trigonometry). This elegant equation reveals a profound connection, often cited for its beauty and fundamental role in fields from engineering to physics.
