Tangents are drawn from the point P(3,4) to the ellipse x^(2)/9+y^(2)/4=1 touching the ellipse at point A and B. Q. The coordinates of A and B are

Tangents are drawn from the point P(3,4) to the ellipse x^(2)/9+y^(2)/4=1 touching the ellipse at point A and B. Q. The equation of the locus of the points whose distance from the point P and the line AB are equal, is

Tangents are drawn from the point P(3,4) to the ellipse (x^2)/(9)+(y^2)/(4)=1 touching the ellipse at points A and B. The equation of the locus of the point whose distance from the point P and the line AB are equal, is:

Tangents are drawn from a point P(6,sqrt(5)) to the ellipse (x^(2))/(25)+(y^(2))/(16)=1 touching the ellipse in the points Q and R. The angle between PQ and PR is
