This math topic focuses on converting complex numbers from rectangular form to polar form, specifically finding the modulus and the argument in degrees. Each question presents a complex number, and students are required to identify or calculate its modulus (the distance from the origin to the point in the complex plane) and its argument (the angle from the positive real axis to the line that connects the origin to the point), with the angle measured in degrees. The topic is part of a broader unit on complex numbers.
