4 Cauchy’s integral formula
Topic 4 NotesJeremy Orloff4 cauchy s integral IntroductionCauchy s theorem is a big theorem which we will use almost daily from here on out. Rightaway it will reveal a number of interesting and useful properties of analytic functions. Morewill follow as the course you learn just one theorem this week it should be cauchy s integral formula !We start with a statement of the theorem for functions. After some examples, we ll give ageneralization to all derivatives of a function. After some more examples we will prove thetheorems. After that we will see some remarkable consequences that follow fairly directlyfrom the cauchy s cauchy s integral for functionsTheorem ( cauchy s integral formula ) SupposeCis a simple closed curve and thefunctionf(z) is analytic on a region containingCand its interior.
where, C is a simple closed curve, oriented counterclockwise, z is inside C and f(w) is analytic on and inside C. Example 4.6. Evaluate I= Z C e2z z4 ... In an upcoming topic we will formulate the Cauchy residue theorem. This will allow us to compute the integrals in Examples 4.8-4.10 in an easier and less ad
