therefore we may assume this value equal to—B^. Then the equation becomes This form is preferred to the former one on account of itssimilarity to the equation of the ellipse,—the difierence is only inthe negative value of B^. Because A^—c^ =—B^, A^+B^ —c^. Now to show the geometricalmagnitude af B,… … THE HYPERBOLA.PROPOSITIO^N^ n.
