# NCERT Solutions Class 11 Maths Chapter 11 Conic Sections

NCERT solutions for Class 11 maths Chapter 11 Conic Sections sheds light on the types of curves commonly known as ellipses, parabolas, circles, and hyperbolas. These curves are known as conic sections or conics, which are obtained when a plane intersects with a double-napped right circular cone. Such curves are important in a wide range of applications, such as in the reflectors of flashlights, the study of planetary motion, antenna and telescope design. These NCERT solutions Class 11 maths Chapter 11 aim at providing information about the different types of curves as mentioned above with relevant practical examples.

Various kinds of conic sections are obtained depending on where the intersecting plane with respect to the cone is and what angle it makes with the vertical axis of the cone. This intersection can be at the vertex of the cone or on any other part of the nappe, above or below the vertex. These curves are critical tools for designing applications to explore space as well as study the behavior of atomic particles. More facts and information about these can be read in the pdf file of the Class 11 maths NCERT solutions Chapter 11 Conic Sections given below and also download the exercise-wise solutions provided in the links below.

## List of Formulas in NCERT Solutions Class 11 Maths Chapter 11

The different curves talked about in this chapter have their own unique standard equations, as well as many formulas to determine the different parameters. Students are advised to pay attention to the derivation of these formulas as well, which will benefit them in understanding the underlying concepts. It is highly recommended that kids make well-organized formula charts which will give them a quick recap of these concepts whenever required. The key to solving this chapter successfully is by memorizing the formulas. Some important ones covered in NCERT solutions for Class 11 maths Chapter 11 are given below :

**Standard Equation of Circle :**If C (h, k) is the center and r is the radius of a circle, while P(x, y) is any point on the circle, then (x – h)^{2}+ (y – k)^{2}= r^{2 }

**Standard Equation of Ellipse :**x^{2}/b^{2}+ y^{2}/a^{2}= 1 wherein the center of the ellipse is the origin and ‘b’ and ‘a’ are the X and Y intercepts respectively.

**Equation of hyperbola with foci on x-axis :**x^{2}/a^{2}- y^{2}/b^{2}= 1 where center is at the origin and ‘a’ is the distance from center to vertex and ‘c’ is the distance from center to foci and b^{2}= c^{2}- a^{2}
