2. In each case, write the function f(z) in the form f(z) = u(x, y) + iv(x, y): z² (a) f(z)=z³+z+1; (b) f(z) = == (z =0). Suggestion: In part (b), start by multiplying the numerator and denominator by z. Ans. (a) f(z) = (x³ - 3xy² + x + 1) +i (3x²y - y³ + y); x3 - 3ху2 y³ - 3x²y x² + y² x² + y² (b) f(z) = +i Z
