## NCERT Solutions for Class 12 Maths Chapter 10: Terms and Definitions

Vector: Those quantities which have magnitude, as well as direction, are called vector quantities or vectors.

• Note: Those quantities which have only magnitude and no direction, are called scalar quantities.

Representation of Vector: A directed line segment has magnitude as well as direction, so it is called a vector.

Magnitude of a Vector: The length of the vector is called the magnitude of a vector.

Position vector: A straight line having one end fixed to a body and the other end attached to a moving point and used to describe the position of the point relative to the body is the position vector. As the point moves, the position vector will change in length or in direction or in both length and direction. Direction Cosines: If α, β and γ are the angles which a directed line segment OP makes with the positive directions of the coordinate axes OX, OY and OZ respectively, then cos α, cos β and cos γ are known as the direction cosines of OP and are generally denoted by the letters l, m and n respectively. #### Types of Vectors~~

Null vector or zero vector: A vector, whose initial and terminal points coincide and magnitude is zero, is called a null vector.

Unit vector: A vector of unit length is called a unit vector

Collinear vectors: Two or more vectors are said to be collinear if they are parallel to the same line, irrespective of their magnitudes and directions.

Coinitial vectors: Two or more vectors having the same initial point are called coinitial vectors.

Equal vectors: Two vectors are said to be equal if they have equal magnitudes and the same direction regardless of the position of their initial points.

Negative vector: Vector having the same magnitude but opposite in direction of the given vector, is called the negative vector
