The vector AP is rotated about by degrees and is subsequently rotated about by degrees. a. Give the rotation matrix that accomplishes these rotations in the given order. b. What is the result if 0 = 45 and = 60? A frame {B} is initially with a frame {A}. We rotate {B} about by . Next, we rotate the resulting frame {B} about by 0 degrees. Finally, we rotate the resulting frame {B} about 2B by $ + 0. Determine the 3 x 3 rotation matrix, R, which will change the description of a vector P in frame {B}, BP, to a frame {A}, 4P.
