(a) This question concerns transformations using matrix multiplication. (i) Formulate the matrix that will first rotate by t/3 radians, then scale by a factor of 2 in the x direction. (ii) Formulate the matrix that will first scale by a factor of 2 in the x direction, then rotate by 7/3 radians. (iii) By applying these transformation matrices to the unit square, show that the order of the transformations matter. Plot each transformed unit square. Note: the unit square has vertices (0,0), (1,0), (1,1) and (0,1).
