In this mathematical demonstration the Newton's Law of gravitation is applied to a star orbiting a galaxy. It is not necessary to use the false concept of Dark Matter to calculate the orbital star velocity. The orbital star velocity in a Spiral Galaxy is proportional on the fourth root of the total Galaxy Mass and other Universal Constants only. It does not depend on the orbital radius or the mass of the Star.
