In the theory of learning, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized. Suppose M denotes the total amount of a subject to be memorized and A(t) is the amount memorized in time t> 0. Detern differential equation for the amount A(t). (Assume the constant of proportionality is k > 0. Use A for A(t).) dA
