find the equation of the ellipse in the following cases:
Ends of the major axis (0, ±
), ends of the minor axis (±1,0)
Given that we need to find the equation of the ellipse whose ends of major axis are
and ends of the minor axis are (±1,0).
Let us assume the equation of the ellipse as
(b2>a2).

We know that ends of the major axis of the ellipse are (0,±b)
⇒ ![]()
⇒ b2 = 5
We know that ends of the minor axis of the ellipse are (±a,0)
⇒ a = 1
⇒ a2 = 1
The equation of the ellipse is
⇒ ![]()
⇒ ![]()
⇒ 5x2 + y2 = 5
∴ The equation of the ellipse is 5x2 + y2 = 5.
