WebGiven the radii of an ellipse, we can use the equation f 2 = p 2 − q 2 f^2=p^2-q^2 f 2 = p 2 − q 2 f, squared, equals, p, squared, minus, q, squared to find its focal length. Then, the … WebMar 6, 2024 · Solution: To find the equation of an ellipse, we need the values a and b. Now, it is known that the sum of the distances of a point lying on an ellipse from its foci is equal to the length of its major axis, 2a. The value of a can be calculated by this property. To calculate b, use the formula c 2 = a 2 – b 2.
