# Thread: lhopital in complex functions..

1. ## lhopital in complex functions..

so in a complex function
what are the conditions for me doing lhotipal
is it just 0/0 inf/inf linke in real functions
or are the other conditions?

2. The usual proof for this rule in the complex plane requires that the function be defined in a punctured neighborhood of the point in question (not sure if this condition can be relaxed), but other than that no.
