J = T [1.5x²(t) + 0.5u² (t)]dt T Is fixed, and x(t) is free. How we get the last two equations For Part (A) | p*(T) = 0, and the soultion of the state - costate d. e has the form x*(T) = 11(T t)x*(t) + 12 (T — t)P* (t) P*(T) 021 (T− t)x*(t) + 422 (T - t)P*(t) o's are the components for the state- costate transition matrix for the linear, homogenous, const. system x(t) = x(t) - P*(t) P*(t) = −3 x*(t) – P*(t)
