Question:

(a) Show that w = ˆšz has the values

+ i sin W1 cos Vr cos (18) W2 = Vr | cos + T+i sin = -W1.

(b) Obtain from (18) the often more practical formula

(19) Vz = ±[V4(z| + x) + (sign y)i V(|z| + x)]

where sign y = 1 if y ‰¥ 0, sign y = -1 if y < 0, and all square roots of positive numbers are taken with positive sign. Use (10) in App. A3.1 with x = Î¸/2.
