`P` is a variable point on the ellipse `x^2/a^2+y^2/b^2=2\ (a gt b)` whose foci are `F_1` and `F_2`. The maximum area (in `unit^2)`of the `Delta PFF'` is

P is a variable point on the ellipse x^2/(2a^2)+y^2/(2b^2)=1\ (a gt b) whose foci are F and F' . The maximum area (in unit^2) of the Delta PFF' is

P is a variable point on the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=2backslash(a>b) whose foci are F_(1) and F_(2.) The maximum area (in unit' ) of the Delta PFF' is

Let P be a variable on the ellipse (x^(2))/(25)+ (y^(2))/(16) =1 with foci at F_(1) and F_(2)

Let P be a variable on the ellipse (x^(2))/(25)+ (y^(2))/(16) =1 with foci at F_(1) and F_(2)

If P is a point on the ellipse x^(2)/a^(2)+y^(2)/b^(2)=1 whose foci are S, S^(') " then "PS+PS^(')=

P is a variable point on the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 with AA as the major axis. Then the maximum value of the area of triangle APA' is

Let P be a variable point on the ellipse (x^(2))/(25)+(y^(2))/(16)=1 with foci at S and S'. Then find the maximum area of the triangle SPS'
