2 Complex Functions and the Complex functionsIn one-variable calculus, we study functionsf(x) of a real variablex. Like-wise, in Complex analysis, we study functionsf(z) of a Complex variablez C(or in some region ofC). Here we expect thatf(z) will in generaltake values inCas well. However, it will turn out that some Functions arebetter than others. Basic examples of functionsf(z) that we have alreadyseen are:f(z) =c, wherecis a constant (allowed to be Complex ),f(z) =z,f(z) = z,f(z) = Rez,f(z) = Imz,f(z) =|z|,f(z) =ez. The func-tions f(z) = argz,f(z) = z, andf(z) = logzare also quite interesting,but they arenotwell-defined (single-valued, in the terminology of complexanalysis).
