Here's the solution for question 40: Step 1: Identify the complex number. The complex number is z = -i. In the form x + iy, we have x = 0 and y = -1. Step 2: Determine the position of the complex number on the complex plane. Since the real part x=0 and the imaginary part y=-1, the complex number -i lies on the negative imaginary axis. Step 3: Calculate the amplitude (argument). For a complex number z = x + iy, the argument (z) is the angle it makes with the positive real axis. When z lies on the negative imaginary axis, the angle is -()/(2) (or (3)/(2)). The principal argument is typically in the range (-, ]. Therefore, Amp(-i) = -()/(2). Step 4: Match the result with the given options. The calculated amplitude is -()/(2), which corresponds to option (B). The final answer is B. That's 2 down. 3 left today — send the next one.
