Line 184: As with the real exponential function (see {{slink\|\|Functional equation}} above), the complex exponential satisfies the functional equation <math display=block>\exp(xz+yw)= \exp(xz)\cdot \exp(yw).</math> Among complex functions, it is the unique solution which is [[holomorphic]] at the point {{tmath\|1= xz = 0}} and takes the derivative {{tmath\|1}} there.<ref>{{cite book \|last=Hille \|first=Einar \|year=1959 \|title=Analytic Function Theory \|volume=1 \|place=Waltham, MA \|publisher=Blaisdell \|chapter=The exponential function \|at=§ 6.1, {{pgs\|138–143}} }}</ref> The [[complex logarithm]] is a [[left inverse function\|right-inverse function ]] of the complex exponential:
