Figure shows elliptical path abcd of a planet around the sun S such that the area of triangle csa is $\displaystyle \frac{1}{4}$ the area of the ellipse. (See figure) With db as the semimajor axis, and ca as the semiminor axis. If $\displaystyle t_1$ is the time taken for planet to go over path abc and $\displaystyle t_2$ for path taken over cda then :
