comment Limit of a 0/0 function
@Hans $g'$ can be zero if $f'$ is zero, because you just have another L'Hospital's case and take $f''/g''$ Otherwise, just compute the limit normally.

comment Limit is found using polar coordinates but it is not supposed to exist.
It's odd - this conflicts with what I was taught last semester, that converting to polar is a foolproof way of proving a limit exists.
