NCERT Solutions Class 11 Maths Chapter 11 Exercise 11.1 Conic Sections
NCERT solutions for Class 11 maths Chapter 11 exercise 11.1 Conic Sections explains the sections of the cone with well-illustrated diagrams and terms like upper nappe, lower nappe, generator, and axis, so as to lay the foundation for the understanding of the curves. Further, it moves to the logic that if the plane intersects the nappe at any point except the vertex of the cone, then the following conditions arise :
- If β = 90 degrees , the section formed is a circle
- When α < β < 90 degrees , an ellipse is formed
- When β = α; a parabola is formed
- When 0 ≤ β < α; the plane cuts through both the nappes and the curves of intersection is a hyperbola
The NCERT solutions Class 11 maths Chapter 11 exercise 11.1 consists of 15 questions of which 11 are short and 4 are long answer type questions.
This section further talks about the degenerated conic sections, i.e., regarding the different cases when the plane cuts at the vertex of the cone, resulting in a point and straight line of a degenerated hyperbola. The students will also study an important equation of the 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 the equation of the circle is given by
(x – h) 2 + (y – k) 2 = r 2
