## Topics Covered in RS Aggarwal Solutions for Class 12 Chapter 22 Vectors and Their Properties

Introduction to Vectors:

If an object or value exhibits both magnitudes as well as direction, it is termed as a Vector. Any given vector can be identified by a line with an arrowhead. In such a line denoting a vector, the length is given by the magnitude of the vector and the direction is denoted by the arrowhead. In a case when the direction and magnitude of two given vectors are equal, we may designate the two vectors as equal. The other names of the vector are Euclidean vector, Geometric Vector, and Spatial vector

In Maths, a line representing a vector gives its magnitude through its length and the angle made by it with a given reference is known as the direction component of the vector. The starting point of a given vector is termed as tail while the endpoint which is denoted by the arrowhead is known as the head of the vector.

The vector is used in the simplification of three-dimensional geometry to decipher the complex topics in it. Hence, we may conclude that a vector that has n number of dimensions is an ordered collection of n elements which are termed as the components.

The magnitude of a Vector

In the above example, the distance between the two points A and B respectively give the magnitude of the given vector. The Magnitude of the vector would be denoted as

|AB| or |a|

The point that should be kept in mind is that length is never negative which would mean that the magnitude of any vector is always greater than or equal to 0.

Key Highlight

• If there is a point A (x, y, z) in free space with respect to the origin O with (0, 0, 0) coordinates. Then, the position vector with respect to the origin of A is written as

OA where O would be the tail point and A is the head of the vector.

The magnitude of this vector will be given as  • The angles made by this vector with respect to x, y, and z axes respectively are given as α,β,y And their cosines are denoted as l=cosα, m=cosβ, and n=cosy.
