+\section{Euler’s Identity}
+\begin{equation}
+    e^{i\pi} + 1 = 0
+\end{equation}
+\\
+A very famous equation, Euler’s identity relates the seemingly random values of pi, e, and the square root of -1. It is considered by many to be the most beautiful equation in mathematics.
+
+A more general formula is
+
+\begin{equation}
+    e^{i x} = \cos x + i \sin x
+\end{equation}
+\\
+When x = $\pi$ , the value of $\cos$ x & is -1, while  i$\sin x$  is 0, resulting in Euler’s identity, as -1 + 1 = 0.\\ \\
