Prove sinz is analytic
WebbTo show sinz is analytic. Hence the cauchy-riemann equations are satisfied. Thus sinz is analytic. Is COSZ an entire? The class of entire functions is closed under the composition, so sinz and cosz are entire as the compositions of ez and linear functions. Read More: What reacts with ammonium nitrate?

We went on to prove Cauchy’s theorem and Cauchy’s integral formula. These revealed some deep properties of analytic functions, e.g. the existence of derivatives of all orders. Our goal in this topic is to express analytic functions as in nite power series. This will lead us to Taylor series.
