Homework Help Overview

The discussion revolves around a Fourier Series problem, specifically focusing on the implications of shifting a function defined on the interval (-L, L) to an arbitrary interval (a, b). Participants are exploring the characteristics of even and odd functions in relation to Fourier series representation.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are questioning how to appropriately shift the function f(x) from the interval (-L, L) to (a, b) and what that entails for the Fourier series representation. There is mention of considering the average value of the function over the new interval as a potential approach.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the implications of shifting intervals and how to apply their understanding of Fourier series. Some guidance has been offered regarding writing the Fourier sum explicitly and considering the effects of the shift.

Contextual Notes

There is a hint provided regarding the average value of the function over the interval, but participants express uncertainty about how to utilize this information effectively. The nature of the function's transformation when shifting intervals is also under examination.

Plz find urgent ::Fourier Series problem?
given function on (-L,L)
If f(x) is even(cosine series) ,odd(sine series) ,either(Fourier series)
what f is given on arbitrary interval(a,b) ?

hey chemical.ojas, don't really follow your question, also you shoukld try and attempt a solution and show your working
 


hey lanedance
f(x) is given function its present on (-L,L)
If f(x) is shifted to arbitrary interval (a,b) then what will be the Fourier series.?
then i want cosine and sine series also.

i tried by considering standard Fourier series...but I have no Idea about how to shift the interval?
i have one hint
a intigral b f(x)=area/b-a = average
but i have no idea how to use this hint.I tried a lot on this.
 


so what does it mean to shift f(x) from (-L,L) to (a,b)

does b-a = 2L or is the function stretched/compressed to fit in (a,b)?

either way, to start, I would write you Fourier sum explictly and apply the shift and have a think about what it tells you...
