Homework Statement
hello
in the college we have Fourier series and i have a problem with the integral limits
i add a pdf ( 2 pages only)
my question is: how did he get the integral limits from the question
the limits are from ##-\pi## to ##-\frac{\pi}{2}## for f(x)=-2 as shown in the first page
but he changed the integral from ##\frac{\pi}{2}## to ##\pi## as shown in the second page
also the integral limits for f(x)=2 are changed but why?
