Step 1: Solve Question 1(a). A function f(z) is said to be analytic (or holomorphic) at a point z_0 if its derivative f'(z) exists not only at z_0 but also at every point in some neighborhood of z_0. A function is analytic in an open set if it is analytic at every point in that set. Step 2: Solve Question 1(b). Let f(z) = u(x,y) + iv(x,y) be a complex function, where z = x+iy. The necessary and sufficient conditions for f(z) to be analytic in a domain D are: 1. The
