limit as n approaches infinity for the function ((-1)^n)((5n+7)/(6n+5))

  • calculus -

    multiply both numerator and denominator by 1/n

    then
    Lim (-1)^n (5+7/n)/(6+5/n)

    so as n gets large, the second part becomes (5/6)
    the first part is +-1, depending if n is odd or even.

    there is not a limit. however, the funcion is +- 5/6 and is bounded by those two numbers.
