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

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

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) 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

If the tangent at the point (p,q) to the curve x^(3)+y^(2)=k meets the curve again at the point (a,b), then
