Problem 1: Express the complex function w = x² – y² – 2y + (2x – 2xy)i in terms of z = x + iy and z = x – iy. Find u and e in two ways: using (a) the expression of w in terms of formulas = }(& - i) and = }+i), and (b) the expression of w in terms of z, z. dz x, Y and the E = +i), and (b) the expression of w in terms of z, z.
