If I have the function
$$f(x) = \begin{cases} 1+x, & -L \le x \le 0 \\ 1, & 0 \lt x \le L \end{cases}$$
and I need to determine the points in the interval $ [-4L,4L]$ where the series does not converge uniformly and also where the series converges pointwise, how would I go about doing this?
I have already worked out the Full Fourier Series on $[-L,L]$.
Thanks
