comment Show solution to ODE's fourier series is a series of sines only
Then I don't get it: The ODE itself has nothing to do with this result? It all comes strictly from the boundary values?

@AndrewD I guess this is theorem: en.wikipedia.org/wiki/… I guess we can't use the theorem since $u$ doesn't necessarily has a bounded variation.

@AndrewD There was actually another segment in the question asking us to explain why we cannot apply that theorem to conclude 2 but since I didn't know the theorem or its terms to quote, I didn't bring it in. Could you give a link to the theorem in question? We are also hinted that we should derive 2 by developing the coefficients of the Fourier series.

@AntonioVargas oh boy, what a blunder. Thanks for setting me straight

@AntonioVargas, on $0$, $e^z=1$ is greater than $3z^{100}=0$ and on $1$ for example, $3z^{100}=3$ and $e^z=e<3$

comment Show that the complex closed line integral $\oint\frac{\mathrm{d}z}{p(z)}$ is $0$ ($p$ is polynomial)
Yeah, the fact that the roots are distinct is relevant to the rest of the question which I didn't present here. I just didn't want to leave it out in case it somehow is needed
