Question

if the foci & vertices of an ellipse be (+1,0) & (+2,0). then minor axis of an ellipse is​

Answer 1

Given: foci & vertices of an ellipse be (+1,0) & (+2,0).

To find: minor axis of an ellipse

Answer:

$c^{2}=a^{2} -b^{2}$

where

c=+1

a=+2

Therefore b=$\sqrt{ (2^{2} -1^{2} )}$

b=1

Length of minor axis=2b

=2

Hence the length of the minor axis is 2 units.
