How do I graph a sequence of partial sums on a TI-89/92/V200

  1. Feb 26, 2006 #1
    I am doing exactly what this article is saying in order to try to graph
    a sequence of partial sums. If I enter the syntax, given below, on the
    home screen, it will list the first 25 terms of the partial sum. How do I
    graph those terms using sequence mode?

    You can just set u1 = the sum from k = 1 to n of 1/k. With sum for uppercase sigma, you would let u1(n) = sum(1/k, k, 1, n) You don't need to use the seq command.
