The area of triangle formed by the tangents from point (3, 2) to hyperbola and the chord of contact w.r.t. point (3, 2) |
(8) Hyperbola is or Equation of tangent is (1) It passes through (3, 2) Or Solving we get values of as and Equation of tangent (1) for Or On taking sign point does not satisfy the equation of tangent therefore rejecting sign. Hence equation of tangent is (2) Now equation of tangent (1) for is rejecting (+) sign (since taking (+) sign point does not satisfy this equation) Hence, equation of tangent is (3) Now equation of chord of contact w.r.t. point is Or Or (4) Solving (2) and (4); Solving (3) and (4); Now vertices of triangle are sq. units |
