Question -
Answer -
Given:
We need to find the eccentricity of an ellipse.
(i) Iflatus – rectum is half of its minor axis
We know that the length of the semi – minor axis is b andthe length of the latus – rectum is 2b2/a.
2b2/a = b
a = 2b …. (1)
By using the formula,
We know that eccentricity of an ellipse is given as
(ii) Iflatus – rectum is half of its major axis
We know that the length of the semi – major axis is a andthe length of the latus – rectum is 2b2/a.
2b2/a
a2 = 2b2 …. (1)
By using the formula,
We know that eccentricity of an ellipse is given as
