I think the hint on the Tutorial slides have the rotations in the wrong order. To get from the body frame to the world frame we should go backwards with the rotations, so for YXZ euler angles we would have rotateVec(rotateVec(rotateVec(v_body,z),x),y). However, the tutorial slides show it reversed.
