Hi! How can I minimize my fucntion in region? The fucntion give me NDSolve, but i cant select right syntax for minimize function.

Minimize[y1[t]/.sol, tE{3,10}], Minimize[{y1[t]/.sol, 3<=t<=10}, t}]
  • dont work...

Since your answer lacks many details I can only guess where it goes wrong. I presume you have something like:

sol = NDSolve[...........,y1];

I guess you can find the minimum of this like so:

    f = y1 /. First[sol];
    FindMinimum[f[t],{t,6,3,10}]

Without an example it is very hard to guess!
