If the line `l x+m y+n=0` cuts the ellipse `((x^2)/(a^2))+((y^2)/(b^2))=1` at points whose eccentric angles differ by `pi/2,` then find the value of `(a^2l^2+b^2m^2)/(n^2)` .

If the line lx+my+n=0 cuts the ellipse ((x^(2))/(a^(2)))+((y^(2))/(b^(2)))=1 at points whose eccentric angles differ by (pi)/(2), then find the value of (a^(2)l^(2)+b^(2)m^(2))/(n^(2))

If the line Ix + my +n=0 cuts the ellpse (x^(2))/(a^(2))+(Y^(2))/(b^(2))=1 in point eccentric angles differ by pi//2 , then

If the line Ix + my +n=0 cuts the ellpse (x^(2))/(a^(2))+(Y^(2))/(b^(2))=1 in point eccentric angles differ by pi//2 , then

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

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

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

Show that the tangent to the ellipse x^2/a^2+y^2/b^2=1 at points whose eccentric angles differ by pi/2 intersect on the ellipse x^2/a^2+y^2/b^2=2

The line L x+m y+n=0 is a normal to the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 , if
