Question

Find the equation for the ellipse that satisfies the given conditions:

Ends of major axis (±3, 0), ends of minor axis (0, ±2)

Sum

Solution

Ends of major axis (±3, 0), ends of minor axis (0, ±2)

Here, the major axis is along the x-axis

Therefore, the equation of the ellipse will be of the form `x^2/a^2 + y^2/b^2 = 1` where a is the semi-major axis.

Accordingly, a = 3 and b = 2.

Thus, the equation of the ellipse is `x^2/3^2 + y^2/2^2 = 1` i.e. `x^2/9 + y^2/4 = 1`
