Vectors

Vectors are quantities defined by both magnitude and direction, critical in mathematics and physics.

Introduction To Vectors

Vectors are quantities defined by both magnitude and direction, fundamental in mathematics and physics.

Definition Of A Vector

A vector is a quantity characterized by both magnitude and direction, which is crucial in mathematics and physics.

Types Of Vectors

This section covers the various types of vectors, each defined by their unique properties related to magnitude and direction.

Zero Vector

The zero vector is a fundamental concept in vector mathematics, defined as a vector with zero magnitude and no direction.

Unit Vector

Unit vectors are vectors with a magnitude of one, used to represent direction in a coordinate system.

Equal Vectors

Equal vectors are defined as vectors that have the same magnitude and direction.

Negative Vector

A negative vector has the same magnitude as a given vector but points in the opposite direction.

Co-Initial Vectors

Co-initial vectors are vectors that share the same starting point but may differ in direction.

Collinear Vectors

Collinear vectors are vectors that lie along the same straight line, possessing both magnitude and direction.

Coplanar Vectors

Coplanar vectors are those that lie within the same geometric plane, playing a crucial role in vector analysis and problem-solving.
