The original proof is based on Taylor series expansions exponential function ez where complex number and sin cos for real numbers see below. The reason for this that exponential function eigenfunction of operation In electrical engineering signal processing and similar fields signals vary periodically over time are often described combination sinusoidal functions see Fourier analysis these more conveniently expressed sum with imaginary exponents using Euler formula. Substituting r cos sin for eix and equating real imaginary parts this formula gives dr dx . Therefore one can write z ln displaystyle varphi any
