Let I be the purchase value of an equipment and v (t) be the value after it has been used for t years. The value V (t) depreciates at a rate given by differential equation (dV(t))/(dt)= -k(T-t) , where k gt 0 is a constant and T is the total life in years of the equipment. Then the scrap value v(T) of the equipment is _______

Let I be the purchase value of an equipment and v (t) be the value after it has been used for t years. The value v (t) depriciates at a rate given by the differentail equation (dv(t))/(dt)=-k(T-t) , where k gt 0 is a constant and T is the total life in years of the equipment . Then the scrap value v (t) of the equipment is :
