Find: (i) the co-ordinates of foci.
(ii) the co-ordinates of vertices.
(iii) the length of major axis and minor axis.
(iv) the eccentricity.
(v) latus rectum of ellipse.
Find: (i) the co-ordinates of foci.
(ii) the co-ordinates of vertices.
(iii) the length of major axis and minor axis.
(iv) the eccentricity.
(v) latus rectum of ellipse.
The major axis is along the y-axis.
∴ The equation of ellipse in the standard form is ...(i)
It passes through (2, 2)
...(ii)
It passes through (1, 4)
...(iii)
Multiplying both sides of (ii) by 4, we get
...(iv)
Subtracting (iv) from (iii), we get
∴ From (iii),
Hence, from (i), the equation of ellipse is:
