1. The problem statement, all variables and given/known data Compute limit as n-> infinity of a)zn = exp(in^2)/(1+in^2) b)zn = 1/(n + i) 2. Relevant equations ? 3. The attempt at a solution These are 2 examples of a series of questions i have to complete. I can see that i need to calculate the limit for a complex function but i have not come accross this in lectures yet. Could you please point me in the right direction, maybe i need to use a certain rule/law/method?
