Weblog(z) = w ()exp(w) = z; z6= 0 : However, since exp is many-to-one, this makes the complex logarithm multiple valued. Since exp is the cartesian-to-polar coordinate map but with exponential radial scaling, the formula for the complex logarithm must be log(z) = lnjzj+ iargz: Indeed this is multiple-valued, since arg is de ned only modulo 2ˇZ ...
