You can download here the recorded temperatures in Montreal on June first 2010 in an excel table). Fit the data set using the model T=a, + ay sin 27t + a2 cos 2nt where T is the temperature in degree Celsius and t is the time of the temperature measurement in fraction of days (e.g. at 12PM (noon) t = 0.5). Use 16 digits in your calculations and give the answers with at least 5 significant digits ao = ai = a2 = The root mean square error RMSE is
