The equation of the chord joining two points (x 1 , y 1 ) and (x 2 , y 2 ) on the rectangular hyperbola xy = c 2 is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The mid point of the chord is 
.
The equation of the chord in terms of its mid point is T = S'
⇒ ⇒ x(y 1 + y 2 ) + y(x 1 + x 2 ) = (x 1 + x 2 ) (y 1 + y 2 )
⇒ ⇒ 
.
