Let a∈[0,1). I want to show that limn→∞nan=0
My try : nan=ne−(loga)n
and the limit is +∞+∞
Hence by l'Hopital's rule we have that
limn→∞1−(loga)e−(loga)n=1−∞=0
Is there any other way to compute this limit ? thanks!
I have injection f:A→B and I want to get bijection. Can I just resting codomain to f(A)? I know that every function i...
