Source Code

```clc, clear all, close all %% Question a fprintf("***** QUESTION a) *****\n"); Ti = 25; % Initial temperature F = 10; % Ambient temperature K = 0.05; % Conduction coefficient dt = 1; % Time step % Declare the tie vector t = 0:dt:100; % Create a vector T that will store the temperatures for each tim step T = zeros(length(t),1); T(1) = Ti; % Now calculate for i = 1:length(t)-1 T(i+1) = T(i) + K*dt*(F-T(i)); end % Now plot figure plot(t, T), grid on xlabel('Time (minute)') ylabel('Temperature (ºC)') title('Temperature vs Time'); % Display fprintf("The temperature at t = %d minutes is T = %.2f ºC\n", t(end), T(end)); %% Question b fprintf("\n\n***** QUESTION b) *****\n"); % Variable to store the sum terms_sum = 0; % Now compute for k = 1:15 terms_sum = terms_sum + (5*k^2 - 2*k); end % Display fprintf("The sum of the first 15 terms in the series is %d\n", terms_sum);```
