Q. Find the argument of the complex number −33+0i in the interval 0≤θ<2π. Express your answer in terms of π.Answer:
Definition of Argument: The argument of a complex number is the angle the line representing the number makes with the positive real axis in the complex plane. The complex number given is −33+0i, which lies on the negative real axis.
Identification of Quadrant: Since the complex number is purely real and negative, the argument is not in the first quadrant 0 to π/2) or the second quadrant π/2 to π), but it is on the line that divides the second and third quadrants, which corresponds to an angle of π.
Calculation of Argument: The argument of the complex number −33+0i is therefore π radians, which is within the specified interval of 0 \leq \theta < 2\pi.
