Pi.Mathematika | Math Learning on Instagram: "Euler’s identity, written as e^iπ + 1 = 0, is often called the most beautiful equation in mathematics because it connects five fundamental constants—e (the base of natural logarithms), i (the imaginary unit), π (the ratio of a circle’s circumference to its diameter), 1 and 0—in a single, elegant expression. What makes it so profound is that these constants come from completely different branches of mathematics: exponential growth, complex numbers, ge
