Homework Help: How do I graph a summation using a TI 89?

  1. Mar 11, 2009 #1
    I know how to write it out in the general window, but not in the graphing window (there's no summation option in the graph feature). Is there a way to import it or another way?

    Change the graphing mode to sequence.

    you could try RTFM.

    (hint: there's a MODE button on the 89. You're trying to change the graph MODE. hmmmm)
