Question

Z = 3i, find the argument. Give explanation.​

Answer 1

Answer:

An argument of the complex number z = x + iy, denoted arg(z), is defined in two equivalent ways: Geometrically, in the complex plane, as the angle φ from the positive real axis to the vector representing z. The numeric value is given by the angle in radians and is positive if measured counterclockwise.The angle from the positive axis to the line segment is called the argument of the complex number, z. The complex number z = 4+3i is shown in Figure 2. It has been represented by the point Q which has coordinates (4, 3). The modulus of z is the length of the line OQ which we can find using Pythagoras' theorem.
