So after the Template ive been using for years now runs out of compile time on overleaf regularly I want to switch to an editor that i run on my pc. Any recommendations for a previous Overleaf user who especially liked the way it let me preview my doc with a quick compile?
So im kinda stumped why the coefficients in this series expansion of my boundary condition take this form, looks very similar to the sin coefficients of a fourier series but why can i assume that the cos coefficients are 0 and the series still converges?
why i can take the sinh part outside i understand and if i exclude that its just the fourier coefficients but its missing the others, which since psi is an arbitrary function shouldnt be 0 but we also dont have a proper fourier series in my solution.
