But then how would you justify the "double the integral" in computing the incomplete series coefficients?
To deal with incomplete series (sin or cosine) we use complete series on $[-l,l]$.

Complete Fourier series are used on any interval of the length $2l$ and formulae are the same (with integral over interval), but for incomplete ones interval must be either $[0,l]$ or $[-l,0]$, If it is not so––shift the origin.

In Promblems for 4.3 questions 4,5 ask for expansion on $[0,\pi]$. Are the same formulae valid there? or do we have to first make the change of variable or other manipulation? In particular for function such as $x(\pi-x)$, is there any trick that can shorten the direct computation?

Thanks!

MAT244--Announcements / TT1 papers

TT1 grades are on BlackBoard

Papers will be returned at Lecture sections. We planned to do it on Tutorial sections, but too many students failed to write properly their Tutorial sections (time slot instead of code does not cut).



Term Test 2 papers will be returned at Tutorial sections first, and only one or two weeks later––on Lecture sections.

Because too many students failed to write properly their tutorial sections, papers will be distributed at lecture sections.

Okay, thanks.

Could we be able to pickup our test papers before our own tutorials? My tutorial is on Thursday. :o

The obvious answer: when TAs finish grading and upload marks
