Abstract:By the method of affine geometry,the expression of the maximum value of closed quadratic curves inscribed quadrilateral area by its diagonal slopes is given.The essential relationship between the products of the diagonal slopes of the closed quadratic curves inscribed quadrilateral and its area changes is revealed.
Keywords:analytic geometry  ellipse  circle  inscribed quadrilateral  diagonal line  slope  area  the peak value
