Q
Q: If z = re^(iθ), then the value of |z| is?
Solution:
The modulus |z| = r in the polar form z = re^(iθ).
Steps: 5
Show Steps
Step 1: Understand that z is given in polar form as z = re^(iθ).
Step 2: Recognize that in this form, 'r' represents the modulus (or absolute value) of the complex number z.
Step 3: Recall that the modulus |z| is defined as the distance from the origin in the complex plane.
Step 4: Since 'r' is the coefficient in front of e^(iθ), it directly represents the modulus |z|.
Step 5: Conclude that the value of |z| is simply r.
