3) 40 pts. We want to drill holes on the Adaptor (Fig. 6) by position the drill tip 3.5 mm above the
surface, drill, withdraw, and rotate to the next hole. Given the coordinate xyz shown, use matrix and
matrix algebra to find:
a) Coordinate matrix for the drill tip above hole "c"
b) Rotation matrix, and compute the matrix for the drill tip above hole "b"
c) Coordinate matrix for the drill tip after drilling 2 mm below the bottom surface of hole "b"
