Compairson test.

  1. Oct 8, 2013 #1
    1. The problem statement, all variables and given/known data

    Use comparison test to see if the integral is convergent or divergent.

    2. Relevant equations

    integral [1,∞] (2+e^(-x))/x

    3. The attempt at a solution

    My books says that (1+e^(-x))/x is divergent and since my integral is bigger it is divergent also.
    TRUE OR FALSE? Thanks for the help

    Compare your integral with ##\int_1^\infty \frac 2 x~dx##.

    Your integral also Diverges. So it diverges I like yours better though.
    I have another one I will post in another forum. In a bit. Thanks.
