Let S and S'' be the fociof the ellipse `(x^(2))/(a^(2))+(y^(2))/(b^(2))=1` whose eccentricity is i.e. P is a variable point on the ellipse. Consider the locus the incenter of `DeltaPSS''`
The eccentricity of the locus oc the P is

Let S and S'' be the foci of the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 whose eccentricity is i.e. P is a variable point on the ellipse. Consider the locus of the incenter of DeltaPSS'' The maximum area of recatangle inscribed in the locus is

Locus of mid-point of the focal chord of ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 with eccentricity e is

P and Q are two points on the ellipse (x^(2))/(a^(2)) +(y^(2))/(b^(2)) =1 whose eccentric angles are differ by 90^(@) , then

The points on the ellipse (x^(2))/(25)+(y^(2))/(9)=1 Whose eccentric angles differ by a right angle are

If e' is the eccentricity of the ellipse (x^(2))/(a^(2)) + (y^(2))/(b^(2)) =1 (a gt b) , then

If e is eccentricity of the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 (where,a lt b), then
