2. If we rotate P(2, 3) with 0-30° in anti- clockwise direction relative to point C(1, 2), we obtain P. (sin30° =0.5, cos 30º = 0.9) Please finish the following tasks: (1) Write Point P and C coordinates in homogeneous coordinates; (2' ); (2) Write the rotating matrix R in 3*3 format(2'); (3) Calculate P' with the rotating matrix R and the point C (3' ).
