SUMMARY
The discussion focuses on solving the equation T(t) = 250 - ae^(-bt) to find the constants a and b, given the temperature of a yam in an oven at 250°C. After 30 minutes, the yam's temperature is 150°C and increasing at a rate of 3°C/min. Using Newton's law of cooling, the values of b can be derived as b = ln(10/7)/10, while a can be calculated using the equation a = 70e^(40b). The discussion emphasizes the application of differential equations in thermal dynamics.
