A complex number in polar form is written as \( Z = \rho \angle \theta \), where \( \rho > 0 \) is the magnitude and \( \theta \) is the argument (typically in the range \( [0°, 360°) \)).
Operations:
• Multiplication: \( \rho_1 \angle \theta_1 \times \rho_2 \angle \theta_2 = (\rho_1 \rho_2) \angle (\theta_1 + \theta_2) \)
• Division: \( \frac{\rho_1 \angle \theta_1}{\rho_2 \angle \theta_2} = \frac{\rho_1}{\rho_2} \angle (\theta_1 - \theta_2) \)
• Addition/Subtraction: Convert to rectangular form first.
