FAQs on NCERT Exemplar: Conic Sections (Solved Example) - Mathematics (Maths) for JEE Main & Advanced

1. What are conic sections?
Ans. Conic sections are the curves obtained by intersecting a cone with a plane. They include the shapes of a circle, ellipse, parabola, and hyperbola.
2. How are conic sections used in real life?
Ans. Conic sections have various applications in real life. For example, the shape of a satellite's orbit around the Earth is an ellipse, and the reflectors used in headlights and telescopes are parabolic in shape.
3. How are conic sections related to JEE exam?
Ans. Conic sections form an important part of the JEE syllabus, particularly in the mathematics section. Questions related to conic sections often appear in the JEE exam and require students to apply their understanding of these curves to solve problems.
4. What is the equation of a circle in conic sections?
Ans. The equation of a circle in conic sections is given by (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the coordinates of the center of the circle and r represents the radius.
5. How are conic sections classified?
Ans. Conic sections can be classified based on the eccentricity of the curve. A circle has an eccentricity of 0, an ellipse has an eccentricity between 0 and 1, a parabola has an eccentricity of 1, and a hyperbola has an eccentricity greater than 1.
