Solution

To find the angle in the complex plane, we can follow these steps:

1. Break Down the Problem

We need to determine the angle (argument) of a complex number, which is typically expressed as z=a+bi z = a + bi , where a a is the real part and b b is the imaginary part. The angle can be found using the arctangent function.

2. Relevant Concepts

The angle θ \theta in radians, given the complex number z=a+bi z = a + bi , can be calculated using the formula: θ=tan1(ba) \theta = \tan^{-1}\left(\frac{b}{a}\right) However, we also need to take into account the quadrant in which the complex number lies to give the correct angle.

3. Analysis and Detail

  1. Identify a a and b b from the complex number:
    • Let’s assume that we have z=a+bi z = a + bi with specific values of a a and b b .
  2. Calculate the angle θ \theta :
    • If a>0 a > 0 and b0 b \geq 0 , θ \theta is in the first quadrant.
    • If a<0 a < 0 , add π \pi to the angle.
    • If a>0 a > 0 and b<0 b < 0 , θ \theta is negative and can be calculated directly.
    • If a=0 a = 0 , adjust the angle to π2 \frac{\pi}{2} or π2 -\frac{\pi}{2} depending on whether b b is positive or negative.
  3. Express the angle in radians, ensuring it is within the range of [0,2π) [0, 2\pi) .

4. Verify and Summarize

After calculating the angle, check the angle to ensure it falls within the specified range of 0 0 to 2π 2\pi .

Final Answer

After completing the calculations based on specific a a and b b , round the answer to the nearest thousandth. For example, if we find θ \theta to be 2.356 2.356 radians, that would be our final answer.

Please provide the specific values of a a and b b so I can compute the exact angle for you.
