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 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)

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

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 theta on (x^(2))/(a^(2))+(y^(2))/(b^(2))=1,(a>b) intersects the curve again at phi then
