    contour integration problem

    i'm having trouble trying to evaluate the following contour integration :

    \oint _{C}\frac{ds}{s^{n+1}}

    where the contour C encloses the right half plane .

    i'm having crazy results !! i need an explanation of the work .

    If n\not = 0 then you can find the primitive.
    And so the integral works out to be zero.
