| Abstract: | In this paper, by formulating and transforming the conic equation the author then classifies, simplifies it and determines the standard equation of conic a ccording to the geometric indication of the parameter "t" when a straight line and a conic intersects. This paper solves the complicated operation and the problem of determining the definite location when classifying the conic equation by using parallel translation and votation of coordinate system and invariants. |
