If the tangents TP and TQ be drawn from a point T whose coordinates are (h,k), on the ellipse x²/a² + y²/b² = 1, prove that the area of the triangle TPQ is

i am giving you the steps to go forward with:

find the equation to the pair of tangents using  T1^2=S*S1.....from pair of tangents equation find individual tangent"s equation..............then find the equation of chord of contact PQ using  eqn PQ=T1

solve these three equations simultaneuosly to obtain three points ..............apply area of triangle in determinant form.......then prove your result..........
