[" The Focii of the Ellipse "(x^(2))/(16)+(y^(2))/(12)=1" are "S" and "S^(1)" .The normal at "P" meets the major axis at "Q" .Then "],[PQ^(2)/SP.S^(1)P" is "]

C is the centre of the ellipse (x^(2))/(25)+(y^(2))/(16)=1 and S is one of the foci. The ratio of C S to semi major axis is

If P is any point on the ellipse (x^(2))/(36) + (y^(2))/(16) = 1 , and S and S' are the foci, then PS + PS' =

P is a point on the ellipse (x^(2))/(36)+(y^(2))/(9)=1 ; S,S^(1) are the Foci of the ellipse then SP + S^(1)P =

P is a point on the ellipse (x^(2))/(a^(2)) +(y^(2))/( b^(2)) =1 with foci at S, S^(-1). Normal at P cuts the x-axis at G and (SP)/( S^(1)P) =(2)/(3) then (SG)/( S^(1)G)

The point P((pi)/(4)) lie on the ellipse (x^(2))/(4)+(y^(2))/(2)=1 whose foci are S and S^(1) The equation ofthe external angular bisector of /_SPS^(1)of Delta SPS^(1) is

P is a point on the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 S and S^(1) are foci A & A^(1) are the vertices of the ellipse then the ratio |(SP-S^(1)P)/(SP+S^(1)P)| is

If P is a point on the ellipse (x^(2))/(36)+(y^(2))/(9)=1 , S and S ’ are the foci of the ellipse then find SP + S^1P

If P is a point on the ellipse (x^(2))/(16)+y'(20)=1, whose foci are S and S' Then PS+PS' is equal to

If S and S' are the foci of the ellipse (x^(2))/( 25)+ ( y^(2))/( 16) =1 , and P is any point on it then range of values of SP.S'P is
