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.
 
Y intial condition 1
 
Alright sounds good. I appreciate it dduardo.
