Question

chomd of contast
i)
Slope of chord chard of contact of ( P ) wastot. Jhe anxiliary The chard of convals
is hxtry ( =a^{2}-b^{2}-c(1 i) )
circle is hxtkd slope of chord of ( =frac{-h}{k} )
Nou), ( frac{h b^{2}}{k q^{2}} timesleft(frac{-h}{k}right)=-1 )
( Rightarrow quad h^{2} b^{2}-k^{2} s^{2}=0 )
( Rightarrow frac{h^{2}}{a^{2}}-frac{1 r^{2}}{b^{2}}=0 )
Twolous , P lied on cone of Jho adymptates

# The chords of contact of a point p with respect to a hyperbola and its auxiliary circle are at right angle. Then, the point P lies on a. conjugate hyperbola b. one of the directrix c. one of the asymptotes d. None of these
