Question : 40
Total: 71
Ends of major axis (±3, 0), ends of minor axis (0, ±2)
Solution:
Since, ends of major axis (±3, 0) lie on x-axis.
∴ The equation of ellipse in standard form is
+
Now, ends of major axis = (±3, 0) ⇒ a = 3.
Also, ends of minor axis = (0, ±2) ⇒ b = 2
Hence, required equation of ellipse is
