What straight line y=ax+b best fits the following data in the least-squares sense?

x	1	2	3	4
y	0	1	1	2

i. Formulate the problem in the form Ax=b for appropriate A and b (matrix form).

We want to fit in the function g(x) = a sinx + b cosx for a data set

x 1 1.5 2 2.5

y 1.902 0.5447 0.9453 2.204

x	1	1.5	2	2.5
y	1.902	0.5447	0.9453	2.204

i. Formulate the problem in the form Ax=b for appropriate A and b (matrix form).
