Solving Complex Number Division: 79 Degrees?

Click For Summary

Discussion Overview

The discussion revolves around the calculation of the phase angle resulting from the division of two complex numbers, specifically focusing on the angles associated with those numbers. Participants explore the method of obtaining the phase angle through subtraction and question the correctness of a provided answer.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant questions their calculation of the phase angle, initially arriving at 45 degrees instead of the expected 79 degrees.
  • Another participant suggests that the problem might have been misinterpreted, proposing that the second number should be 52 at an angle of 18 degrees instead of the originally stated values.
  • There is a light-hearted exchange regarding the potential for extra credit based on identifying the error in the question.
  • Some participants express confusion about the complexity of the topic, indicating a lack of clarity in the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correct interpretation of the problem or the calculation method, and multiple interpretations of the question remain unresolved.

Contextual Notes

The discussion includes assumptions about the angles and their representation in the context of complex numbers, but these assumptions are not explicitly stated or agreed upon by all participants.

I had a question on a test...and I am trying to figure what is wrong...it seems easy...so what am i missing?

What is the phase angle, in degrees, when you divide 62 at an angle of 97 degrees by 18 at an angle of 52 degrees?

I came up with 45...but the answer said 79?

I thought all you did was subtract...97-52?

Hi Jason03! :smile:

Looks like they meant 52 at an angle of 18 degrees! :rolleyes:
 
well than that's a good thing..right?...lol...I need to let my teacher know so I can get the extra points...

Actually you ought to have your teacher give tiny-tim the extra points. He guessed the fault in the question. :smile:

Hi Ouabache! :smile:

Jason03 can have the real points, and I'll have the imaginary points! :wink:

This is too complex for me. :confused:
