Homework Help: Harmonic or p-series

    1. The problem statement, all variables and given/known data
    From the example:
    blah, blah, blah, = 1/n which is divergent (harmonic serics)

    3. The attempt at a solution

    blah, blah, blah, =1/n which is a p-series with p=1, therefore divergent.

    We both get the same answer, but since all the problems in this section are either convergent or divergent, coming up with the right answer doesn't always mean you did it right.

    You're both right. The sum 1/n is the harmonic series, but is it also a p-series with p=1. Hence, both comments are correct.

    Although It depends what you know about the conditions on p for convergence.
