Exercise 1. In this exercise we will compare two different methods of approximating the number e:= 0(1) (technically we don't know yet that the numbers exp(1) and e are the same, but it doesn't matter for this problem). For each n > 0 define the two “error terms": 1 \n an := e-(1+) and bn := exp(1) - Determine the convergence divergence of each of the following series: (1) Emo an (2) Enzo bn When answered correctly, this exercise shows...
