    infinite sum

    Use the inequalities S2m <(or equal) s <(or equal) S2m-1to calculate the infinite sum S= (summation goes to infinity and starts at k=1) (-1)k-11/k! within an error of at most .001
    I really have no idea where to begin. So any help would be much appreciated. thanks

    Re: infinite sum

    k=1,2,....6 are enough to reach error<0.001
