Calculus 8th Edition

Kepler's three laws of planetary motion are described as follows: : (1) Law of orbits: All planets move in elliptical orbits haying the Sun as one focus. (2) Law of areas: A line or radius vector $r(t)$ or a line segment that connects any planet to the sun sweeps out equal areas in equal time of period. (3) Law of periods: The square of the orbital period of any planet is proportional to the cube of the semi-major axis of its orbit.
