The goal of this problem is to fit a trigonometric function of the form f(t) = a sin(t) + b to the data points (0,-6). (,-7), (, -6), (3, 3), using least squares (a) The problem is equivalent to finding the least squares solution to the system Xc = y where X = and c= [a, b] (b) Find the coefficients of the best fit by finding the least squares solution to the system in part (a) a b
