HW #3

Look at 11.7 for more practice with convergence vs. divergence.
11.8 #3,8,9,10,35.
For this you need the "interval of convergence". We didn't discuss this in class -- it just means, find the radius of convergence, then test what happens at x=R and x=-R. (I.e. whether they should be included as the endpoints of the interval of real numbers within the radius of convergence.)
11.9 #7,8,14,35
11.10 #7,8,9,10,27,28
