Two hyperbolas having the same asymptotes with semiaxes interchanged.

Conjugate Hyperbolas


two hyperbolas defined in the same rectangular coordinate system by the equations


where a and b have the same values in both equations. Conjugate hyperbolas have the same asymptotes. The transverse and conju-
