Euler head, also known as Euler's formula, refers to a mathematical expression that establishes a deep relationship between trigonometric functions and complex exponentials. It states that ( e^{i\theta} = \cos(\theta) + i\sin(\theta) ), where ( e ) is the base of the natural logarithm, ( i ) is the imaginary unit, and ( \theta ) is a real number. This formula is pivotal in various fields of mathematics, physics, and engineering, particularly in the study of oscillations and waveforms. Euler's formula is often celebrated for its elegance, especially in the case of ( \theta = \pi ), which leads to the famous equation ( e^{i\pi} + 1 = 0 ).
