NCERT Solutions Class 11 Maths Chapter 11 Exercise 11.2 Conic Sections
NCERT solutions for Class 11 maths Chapter 11 exercise 11.2 Conic Sections sheds light on a parabola which is defined as the set of all points that are in a plane and are at an equal distance from a particular fixed line and a fixed point in that plane. This fixed line is known as the directrix of the parabola and the fixed point is known as the focus, usually represented as ‘F’. Parabola can be visualized as the shape obtained when we throw a ball in the air. The axis of the parabola is defined as the line passing through the focus and perpendicular to the directrix. The intersection point of the parabola and the axis is called the vertex of the parabola. The NCERT solutions Class 11 maths Chapter 11 exercise 11.2 consists of 12 questions of which 9 are short and 3 long answer type questions.
The equation of the parabola is given by y2 = 4ax. The students will learn about one more new term that is the ‘Latus rectum’ of a parabola, which is a line segment that stands perpendicular to the parabola’s axis, and through the focus. Its endpoints lie on the parabola. The exercise questions in the Class 11 maths NCERT solutions Chapter 11 exercise 11.2 Conic Sections are given below :

NCERT Solutions Class 11 Maths Chapter 11 Exercise 11.2 Tips
NCERT solutions Class 11 maths Chapter 11 exercise 11.2 Conic Sections explains how a parabola with respect to the axis of the parabola is symmetric. If the axis of symmetry of the parabola is along the x-axis, and if in the parabola’s equation, the coefficient of x is positive, then the parabola opens to the right; and if this value is negative then the parabola opens to the left. While, if the axis of symmetry is along the y-axis, if the coefficient of y is positive, the parabola opens upwards, while if the coefficient is negative, then it faces downwards.
NCERT solutions Class 11 maths Chapter 11 exercise 11.2 Conic Sections would involve a lot of diagrams, and students must make sure to include these in their practice as it will help in understanding the sums better. It's always a good idea to draw out the problem first and understand the missing elements as it gives a clear picture of how to proceed with problem-solving.
