Answer 19

If you don't need anything major as a proof, you could simply state that p series only converge if s > 2, and seeing as s = 1 in this problem, s < 2, therefore it does not converge. If you want a more complicated proof: http://www.math.unh.edu/~jjp/proof/proof_n.html

your nice

Answer 31

You can use the comparison test by testing another divergent series. If that divergent series is always less than 1/n then that implies 1/n is divergent as well.
