Question : 47
Total: 71
Major axis on the x-axis and passes through the points (4, 3) and (6, 2).
Solution:
Since the major axis is along the x-axis.
∴ The equation of ellipse in standard form is
+
= 1
Since the ellipse passes through point (4, 3)
∴
+
= 1 ... (i)
Also, the ellipse passes through point (6, 2)
∴
+
= 1 ... (ii)
Solving (i) and (ii), we geta 2 = 52 and b 2 = 13
Hence the required equation of ellipse is
+
= 1.
∴ The equation of ellipse in standard form is
Since the ellipse passes through point (4, 3)
∴
Also, the ellipse passes through point (6, 2)
∴
Solving (i) and (ii), we get
Hence the required equation of ellipse is
