FAQs on Ellipse: Examples Video Lecture - Mathematics (Maths) for JEE Main & Advanced

1. What is an ellipse?
Ans. An ellipse is a closed curve that is formed by the intersection of a cone and a plane. It is a set of points in a plane, such that the sum of the distances from any point on the curve to two fixed points (called the foci) is constant.
2. How is the major axis of an ellipse defined?
Ans. The major axis of an ellipse is the longest diameter of the ellipse, which passes through the two foci and the center of the ellipse. It is twice the length of the semi-major axis.
3. What is the relationship between the major axis and the minor axis of an ellipse?
Ans. The major axis of an ellipse is perpendicular to the minor axis. The length of the major axis is always greater than or equal to the length of the minor axis.
4. How can the eccentricity of an ellipse be calculated?
Ans. The eccentricity of an ellipse can be calculated by dividing the distance between the foci by the length of the major axis. It is a measure of how elongated or stretched out the ellipse is.
5. What are some real-life examples of ellipses?
Ans. Ellipses can be observed in various real-life scenarios. Some examples include the orbits of planets around the sun, the shape of satellite orbits, the design of car headlights, and the shape of some sports stadiums, such as baseball and soccer fields.
