Extract

Some years ago, under the heading “Introductory theorems in geometrical conics” (Gazette, XVIII (1934), p. 223), an elementary geometrical treatment was offered of some general properties of conics based on the focus-directrix definition

Other definitions of the conic were not considered nor was the relation of the curve to its auxiliary circle introduced.
