Question

Quizplus · Accepted Answer

Complex numbers are represented in the form of a+bi, where a and b are real numbers and i is the imaginary unit. The phase angle of a complex number is the angle between the positive real axis and the line connecting the origin to the complex number in the complex plane. The magnitude of a complex number is the distance from the origin to the complex number in the complex plane.
