What is vector and what are the basics concepts of vectors
What is vector and what are the basics concepts of vectors: Firstly i will tell you that what is vector. Vector: A vector is represented graphically by a directed line segment with an arrow head. The length of line segment according to the chosen scale correspond to the magnitude of the vector. Rules applicable on vectors: Vectors cannot be added subtracted multiplied and divided by simple arithmetic rule. We graphic and trigonometric rules for vectors. Vectors representations: There are two ways to represent vectors quantities. 1. Symbolic representations 2. Graphical representations. 1. Symbol representation A vector represented by bold letter A. OR A vector may also be represented by putting an arrow above or below the letter as A or A. The magnitude of a vector is also called modulus and is denoted by placing two parallel lines across a vector, i.e. A =A 2. Graphically representations:
