What is the difference between a direction cosines matrix and a rotation matrix? O A direction cosines matrix can do only rotations around one coordinate axis at a time, either around x-, y- or z-axis. While a rotation matrix can do any rotation. O A rotation matrix can do only rotations around one coordinate axis at a time, either around x-, y- or z- axis. While a direction cosines matrix can do any rotation. O A rotation matrix is the same thing as a direction cosines matrix O A rotation matrix can only be 3x3, while a direction cosines matrix can be either 2x2 or 3x3.
