   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.
