Nontangential limit
= Nontangential limit
{title2=$\angle\lim_{z\to0}f(z)$}
A boundary limit taken while approaching within a cone that stays away from tangency. At zero in the <complex upper half-plane>, every fixed cone $|\operatorname{Re}z|\leq A\operatorname{Im}z$ is allowed. A <nontangential limit> need not be a limit along all paths approaching the boundary.
