As seen highlighted below (from wiki), the direction cosines are the ratio of the dot product of a vector with the standard basis vectors, resulting in scalars, to the magnitude of the vector, which is a scalar. A scalar divided by a scalar results in a scalar. Therefore, the direction cosines of a vector are scalar quantities, is that correct?

Are direction cosines scalar or vector quantities, and why?
