A Specific Construction of a Conic from an Ellipse
Lee, J. Todd
Mathematics Teacher, v98 n2 p98 Sep 2004
The interesting construction of a conic from an ellipse given by Manuel Santos-Trigo is evaluated. The validity of the conclusion that the locus is a conic section, the nature of which is determined in a simple way by the location of the variable point R relative to its center point O and the major vertices of the ellipse are proved.
