Calculators ODEs on the TI-89

  1. Sep 20, 2005 #1
    Does anyone know how to graph the integral curves / slope fields of ODEs on the 89? I don't have a manual for mine, and suppose a few of you are quite familiar with it.

    Thanks in advance.

    MODE=>Graph=>Diff Equations
    DIAMOND=>F1
    y1'=5t
    yi1=1

    or you can just solve for the equation directly like this:

    desolve(y''=(-g/l)y',t,y)

    What is the Yi1 for?

    Thanks for the response.
