Updated it to...
ode := diff(y(t), t) = .01(y(t)-1)(y(t)+2)
IC: ic :=[seq(y(0)=.25*n,n=-10..10)]:
Now, trying to plot...
DEplot(ode, y(t), t = -10 .. 10,y=-10..10, ic)
and I get nothing... no error, no graph... nothing.
I can't seem to figure this out... I don't think it's taking my initial conditions correctly. But anyways, I've got to take the following ODE, plot the solution that will satisty the initial conditions.
ODE: ode := diff(y(t), t) = (0.1e-1*(y(t)-1))*(y(t)+2)
IC: ic :=[seq(y(0)=.25*n,n=-10..10)]:
Then I proceed to plot by...
DEplot(ode, y(t), t = -10 .. 10, ic)
but I get the following error "Error, (in DEtools/DEplot/CheckInitial) the 'number' option must be specified before initial conditions"
Anyone nudge me in the right direction?
Thanks.
