# Math Help - Complex limits and addition

1. ## Complex limits and addition

Hey guys.
I'm going through some questions and came across this one which I've got absolutely no clue how to do. Is anyone able to help out?

It mentions making use of two cases, a being part of C, then a = inf

Absolutely no idea what to do as I said, which is giving me the earther kits

For $a\neq \infty$ use the standard $\epsilon/2$ and $\min \{\delta,\delta'\}$ arguments. For $a=\infty$ use the standard $\epsilon/2$ and $\max \{R,R'\}$ arguments.
