Consider the ellipse x ^2 ^2 + y ^2 ^2 =1 where (0, / 2) . Which of the following quantities would vary as varies?
Options
- ADegree of flatness
- BOrdinate of the vertex
- CCoordinates of the foci
- DLength of the latus rectum
Correct answer
D. Length of the latus rectum
Step-by-step solution
aligned & e ^2=1- ^2 ^2 = ^2 ( as ^2 ^2 ) & hence e= ; vertex (0, ) & foci =(0,1) ; l( LR )= 2 b^2 a = 2 ^2 =2 aligned
