comment Find the limit of a Riemann Sum
In this case(division of two polynomial of the same degree say $s$) the limit is the division of the coefficients of the $n^s$

comment PDEs for string deflection.
We exclude the positive case physically or mathematically. In this case the the function $F$ will be $Ae^{\alpha x}+Be^{-\alpha x}$ which has at most one zero while $u(x,0)$ has two zeros.
