    I'm not sure I understand your question. How can angular displacement NOT be finite? Angular velocity, just like velocity is, by definition, a vector quantity.

    finite angular displacement do not obey the associative and commutative law of vector addition,so is not a true vector.is it so?infinitesimal angular displacement is a vector.is it correct?
