Hi,
I have faced another problem if you could answer me I would appreciate your kind help.
I have introduced this function
B[t_, Y_] :=
1/2 M^2 Y ^((1 COMPLICATED FUNCTION OF Y AND t)
then
F[t_, u_] :=
Block[{Y}, t*B[t, Y] /. Solve[1  (1  u) Y == Y^2, {Y, 0}]]
Minimize[F[.1, u], {u}]
as can be seen does not work when I want to minimize it with respect to u.
THANKS
