Find the radius of convergence of the power series:
My answer; 0 using
Find the limits, if they exists, of
i) as n tends to infinity
ii) as n tends to 0
My working i) pretty certain its infinity but not sure how to show it
ii) no idea on this one.
ok I got 0.5, 0 and non exsistent respectively. Can I use l'hopital's rule for sequences or just functions? Thank for the help.
I am doing an analysis exam next month on limits of sequences, series and functions. I don't suppose you have any tips as I often feel like i'm stumbling in the darkness trying to figure out which method to use.
