What will you learn in Chapter 11 Conic Sections?

In this Chapter, we will study circles, ellipses, parabolas and hyperbolas. These curves are in fact, known as conic sections or more commonly comics because they can be obtained as intersections of a plane with a double-napped right circular cone. These curves have a very wide range of applications in fields such as planetary motion, design of telescopes and antennas, reflectors in flashlights and automobile headlights, etc.. 

The main concepts which will be covered in this chapter are:

1. Visualisation of cross-sections of a cone and a plane.

2. Definition of circle and equation of a circle when its centre and radius are known.

3. Definition and different terms related to parabola like Focus, Vertex, Axis, Directrix, Latus rectum, etc.

4. Standard equation of four parabolas along with their graphs.

5. Length of Latus rectum.

6. Definition and different terms related to Ellipse like Focus, Vertex, Axis, Directrix, Latus rectum, etc.

7. Major and Minor axes of the ellipse.

8. Relationship between semi-major axis, semi-minor axis and the distance of the focus from the centre of the ellipse.

9. The eccentricity of the ellipse.

10. Standard equations of the ellipse and the length of the Latus rectum. Definition and different terms related to Hyperbola like Focus, Vertex, Axis, Directrix, Latus rectum, etc.

11. Transverse and Conjugate axes of the ellipse.

12. Relationship between semi-major axis, semi-minor axis and the distance of the focus from the centre of the hyperbola.

13. The eccentricity of the hyperbola.

14. Standard equations of hyperbola and the length of Latus rectum.
