find the locus of the mid points of the chord of the hyperbola x 2 /a 2 -y 2 /b 2 =1 which subtend a right angle at the origin.
 
 
consider the mid to be a point P (X 0, Y 0 ) now use the formula S 1 =S 11 you will get the equation of chord with its mid point. then homogenise this equation with the equation of given...
