13.4 Explain why Rez (0:1) (= 1) dz ~(0;1) ( ) cannot be evaluated by applying Cauchy's integral formula with f(z) = Rez. Prove that Rez coincides with (z+z)/2 when || = 1. Hence evaluate the given integral. 13.4 Explain why Rez (0:1) (= 1) dz ~(0;1) ( ) cannot be evaluated by applying Cauchy's integral formula with f(z) = Rez.
