$$ \zeta'(x)/\zeta(x) = - 3/4 $$
numerically. I'm expecting/hoping for an answer between 1 and 10.
I tried
$\texttt{ find_root(diff(zeta(x))/zeta(x) + 0.75, 2, 40)}$,
but this returns 0.0. I don't know what that ratio of zeta functions looks like, so it's possible there isn't a root, but I don't see why I'm getting an answer outside the specified interval.
Can anyone help find the true root? Thanks.
