WebIn three dimensions, angular velocity can be represented by a pseudovector because second rank tensors are dual to pseudovectors in three dimensions. Since the angular velocity tensor W = W ( t) is a skew-symmetric matrix : its Hodge dual is a vector, which is precisely the previous angular velocity vector . Exponential of W [ edit]
