Complex variables

Please see the attached file for full problem description. --- 5. Write |exp (2z + i) | and | exp (iz2) | in terms of x and y. Then show that | exp (2z + i) + exp (iz2) | ≤ e2x + e-2xy. (exp means exponential function)

Complex variables

Please see the attached file for full problem description. --- 3. Show that (a) Log (1 + i)2 = 2 Log (1 + i) (b) Log (-1 + i)2 ≠ 2 Log (-1 + i).

Complex variables

Please see the attached file for full problem description. --- 5. Show that (a) the set of values of log(i1/2) is (n + ¼) π i (n = 0, ± 1, ±2, …) and that the same is true of (1/2)log i; (b) the set of values of log(i2) is not the same as the set of values of 2log i.
