sorry, some mistake. it should from 0 to T so
df/dQ is c1*Int(1,from 0 to T) is c1*T.
if P(Q)
Let U(s,Q)= Int(x0(t)+Q, from 0 to s)
Than it is f(Q)=c1*U(P(Q),Q)-c2*U(T,Q)+c2*U(P(Q),Q)
so df/dQ= (c1+c2)*(x0(P(Q))+Q)+(c1+c2)*P(Q)-c2*T
=(c1+c2)*2Q -c2*T -(c1+c2) x0^(-1)(Q).
where x0^(-1) means inverse function of x0. |
