Complex exponential Fourier series coefficients?

Click For Summary

Discussion Overview

The discussion revolves around the calculation of complex exponential Fourier series coefficients. Participants are exploring the steps involved in deriving these coefficients and addressing a specific point of confusion encountered by one member.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant expresses difficulty in progressing beyond a certain point in their calculations of Fourier series coefficients.
  • Another participant requests clarification on the specific steps taken and the point of confusion to provide better assistance.
  • A participant shares their expression for the coefficients, Cn = 3/2 Sa(nπ/2)e-(jnπ)/2, but indicates uncertainty about the next steps.
  • There is a mention of an expected answer being 0 and 3/(jnπ), but it is unclear how to arrive at this result.
  • One participant suggests that the confusion may stem from a possible differentiation error instead of integration when calculating the coefficients.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants are still working through the problem and clarifying steps without a definitive resolution.

Contextual Notes

Participants have not provided complete details of their calculations, and there may be missing assumptions regarding the definitions and methods used in deriving the coefficients.

Above is a question I need some help with. I can get to a certain point, but I can't get beyond.
Can somebody with knowledge about this help?

Cn = 3/2 Sa(nπ/2)e-(jnπ)/2
That is where I get up to, but I don't know what to do from there.
The answer given is: 0 and 3/(jnπ)

You need to show your work. It looks like you differentiated instead of integrated when calculating the coefficients.
