If the normal at the point `p(theta)` to the ellipse `5x^(2)+14y^(2)=70` intersects in again the point `Q (2 theta)`, then show that, `cos theta=(2)/(3)`

If the normal at the point P(theta) to the ellipse (x^(2))/(14)+(y^(2))/(5)=1 intersects it again at the point Q(2 theta), then cos theta is equal to (A)(2)/(3)(B)(-2)/(3) (C) (3)/(4) (D) non of these

If the normal at the point P( theta) to the ellipse (x^(2))/(14)+(y^(2))/(5)=1 intersects it again at the point Q (2 , theta) then cos theta is equal to

The normal at a poitn P( theta) on the ellipse 5x^(2) +14y^(2) =70 cuts the curve again at a point Q (2theta) then "cos" theta

The normal at a point P(theta) on the ellipse 5x^(2)+14y^(2)=70 cuts the curve again at a point Q(2 theta) then cos thetahat I

If the normal at the point P(theta) to the ellipse x^2/14+y^2/5=1 intersects it again at the point Q(2theta), then Costheta is equal to (A) 2/3 (B) (-2)/3 (C) 3/4 (D) non of these

If the normal at the point P(theta) to the ellipse x^2/14+y^2/5=1 intersects it again at the point Q(2theta), then Costheta is equal to (A) 2/3 (B) (-2)/3 (C) 3/4 (D) non of these

If the normal at the point P(theta) of the curve x^((2)/(3))+y^((2)/(3))=a^((2)/(3)) passes through the origin then
