    Newton's law of cooling states that the rate of change in the temperature T(t) of a body is proportional to the difference between the temperature of the medium M(t) and the temperature of the body. That is, dT K[M(t) - T(t)], where K is a constant. Let K=0.05 (min) - 1 and the temperature of the medium be constant, dt M(t) = 294 kelvins. If the body is initially at 370 kelvins, use Euler's method with h=0.1 min to approximate...
