gent lines through the ver-tices of conjugate diameters^ is equiva-lent to the rectangle formed hy drawingtangent lines through the vertices of the axes. Remark.—The reader should observe that this proposition issimilar to (Prop. XI,) of the ellipse, and the general equationhere found, and the… … n ANALYTICAL GEOMETRY. On the Asymptotes of the Hyperbola. Definition.—If tangents to four conjugate hyperbolas bedrawn through the vertices of the axes, the diagonals of therectangle so formed and produced indefinitely, are called asymp-totes of the hyperbola. Let AA, BB\ be the axes offour…
