Euler's identity

Euler's identity is a famous equation in mathematics that establishes a profound relationship between the most important constants in mathematics. It is expressed as: \[ e^{i\pi} + 1 = 0 \] In this equation: - \( e \) is Euler's number, approximately equal to 2.71828, which is the base of the natural logarithm. - \( i \) is the imaginary unit, defined as \( \sqrt{-1} \).
