| Abstract: | Using a direct method regarding solution of a equation as a polynomial of cosine, a kind of nonlinear orbital differential equation of a particle exerted by attractive central force following power law is solved. It is pointed out that the orbit of a particle ejected from apsis is a sine spiral. |
