Series Converge or Diverge

  1. Apr 6, 2010 #1
    given the series, determine whether the series converges or diverges:
    (E is my sigma)

    E sin(4/3n)

    Now would it just be the same if i compared 1/n to 3/4n to diverge

    Then could I just say since 3/4n diverges then sin(3/4n) must also diverge?

    I wouldn't really know how to do the algebra for the direct comparison test or limit comparison test with the sin being there. But i can do the algebra for comparing 1/n with 3/4n..help please
