| Abstract: | In the analytic geometry, a chord mid-point path parallel to a non asymptotic directions are discussed in detail, there are many good properties. This article carries on the discussion of the mid-point of the chord of quadratic curve have a fixed point, We get the trajectory equation ,gives some simple applications, and draw several good properties. |
