Euler's identity - Wikipedia
https://en.wikipedia.org/wiki/Euler's_identityFundamentally, Euler's identity asserts that is equal to −1. The expression is a special case of the expression , where z is any complex number. In general, is defined for complex z by extending one of the definitions of the exponential function from real exponents to complex exponents. For example, one common definition is:
