qu 5 i,v

resource ex 9.5 attached 

Ex 9.5: Prove: if f(z) is analytic and real on a domain R then I is a constant function.. Pf: I is analytic and real on √2 => f(x,y) = u(x, y) +².0 namely v(x, y) = 0₁ CR equations hold for I from analyticity on 1}: every ZEN 04 OV = 0 and and Dy = - DV=0 24 = DU = 0 => M(X,Y) = CER = f(x,y)=c, namely if is a constant function.
