real analysis - series is divergent

I want to prove that k=1(1k12k) diverges? I want to do this with the comparison test, but I don't find a divergent series.

An other point I want to ask, if you can do this: k=1(1k12k)=k=11kk=112k? One of this series of the right hand side is convergent, therefore you don't have the undefined case .

How to find limh0sin(ha)h without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
