`LL^(')` is the latus rectum of an ellipse and `Delta S_(1)LL^(')` is an equilateral triangle Then `e=`

LL' is the latusrectum of an ellipse and Delta SLL' is an equilateral triangle.The eccentricity of the ellipse is

In Q.(13) length of the latus rectum of the ellipse is

S and T are foci of an ellipse and B is an end of the minor axis , if STB is an equilateral triangle , the eccentricity of the ellipse , is

If the latus rectum of a hyperbola forms an equilateral triangle with the vertex at the center of the hyperbola,then find the eccentricity of the hyperbola.

If end points of one latus rectum with the point where major axis cuts directrix makes an equilateral triangle then eccentricity of ellipse is sqrt((sqrt(5)-1)/(2))

The lenth of the latus rectum of the ellipse 3x^2+y^2=12 is :

The latus rectum of an ellipse is half of its minor axis. Its eccentricity is :

If the minor axis of an ellipse forms an equilateral triangle with one vertex of the ellipse then e=
