Show that the area of the triangle formed by the two tangents through `P(x_(1),y_(1))` to the circle `S=x^(2)+y^(2)+2gx+2fy+c=0` and the chord of contact of P w.r.t S=0 is `(r(S_(11))^(3//2))/(S_(n)+r^(2))`, where r is the radius of the circle.

Text Solution

Verified by Experts

The correct Answer is:
`=(r(S_(11))^(3//2))/((S_(11)+r^(2)))`
