Textbook Question
Chapter 1, Problem 14P

Newton's law of cooling says that the temperature of a body changes at a rate proportional to the difference between its temperature and that of the surrounding medium (the ambient temperature),

d T d t = k ( T T a )

where T = the temperature of the body ( °C ) , t = time (min), k = the proportionality constant (per minute), and T a = the ambient temperature ( °C ) . Suppose that a cup of coffee originally has a temperature of 70 ° C . Use Euler's method to compute the temperature from t = 0 to 10 min using a step size of 2 min if T a = 20 ° C and k = 0.019 /min .
