I have attached the full question as stated in the problem sheet. I am just stuck in the sketching part.

Ah, yes. You left out the "and" part...I have attached the full question as stated in the problem sheet.

So the period of the waveform is 2l, right? So f(x) should equal f(2l), not f(3l/2)...

According to the belated problem statement, f(x) = f(x + 2l).So f(x) should equal f(2l), not f(3l/2)...

Yeah, thanks Mark. I meant f(x) = f(x + 2l), not = f(x + 3l/2). Trying to type too fast I guess...According to the belated problem statement, f(x) = f(x + 2l).

f(x) = f(x + 2l) becomes f(x) = f(x + 2ℓ)

##\LaTeX##, can also give a good result. Its standard use of a serif font in italics for variables gives ##f(x) = f(x + 2l) ##.

But the script lowercase L can be displayed in ##\LaTeX##. Use "\ell" to get ##f(x) = f(x + 2\ell) ##.

Now I must say that "\ell" looks better written with ##\LaTeX## as \##ell##.
