WebFor instance, f(z)=3z −7z2 +z3 is analytic at every z. Rational functions of a complex variable of the form f(z)= g(z) h(z),whereg and h are polynomials, are analytic everywhere, except at the zeros of h(z). For instance, z2 +1 z −i is analytic except at z = i. In the above example, z = i is called a pole of f(z).
