| Abstract: | We can work out the point of intersection of two conic sections by using degenerate conic in the conic section system. On the extended plane, we may work out four points of intersection of two conic sections including infinite points, using homogenous coodinates.Besides,the author also discusses the relationship between the point of intersection of the conic sections s = 0 and s' = 0 and the characteristic root for the characteristic equation of the conic section system. |
