For this problem, you must consider magnitude and argument of complex numbers geometrically.
The answers are as follows:
r_1 = 16
theta_1 = 3*pi/2
r_2 = sqrt(3)
theta_2 = 5*pi/4
r_3 = 12
theta_3 = pi/3
For this problem, you must consider magnitude of complex numbers geometrically.
For the first part, the answers are |v| = 2, |w| = 3, |z| = 3.
For the second part, the answers are |v + w| = sqrt(2), |w + z| = 2, |z + v| = sqrt(3).
For this problem, you must consider addition and subtraction of complex numbers geometrically. The answer turns out to be s, t, u.
