Question

explain

what is vector ?
​

Answer 1

Answer:

THE QUANTITY WHICH HAVE BOTH MAGNITUDE AND DIRECTION IS CALLED VECTOR.

Answer 2

Answer:

In mathematics, physics, and engineering, a Euclidean vector is a geometric object that has magnitude and direction. Vectors can be added to other vectors according to vector algebra.

Explanation:

Definition:A scalar, generally speaking, is another name for "real number."

Definition: A vector of dimension n is an ordered collection of n elements, which are called components.

Notation: We often represent a vector by some letter, just as we use a letter to denote a scalar (real number) in algebra. In typewritten work, a vector is usually given a bold letter, such as A, to distinguish it from a scalar quantity, such as A. In handwritten work, writing bold letters is difficult, so we typically just place a right-handed arrow over the letter to denote a vector. An n-dimensional vector A has n elements denoted as A1, A2, ..., An. Symbolically, this can be written in multiple ways:

A = <A1, A2, ..., An>

A = (A1, A2, ..., An)

Example: If A = (-2, 1) and B = (-2, 1), then A = B since -2 = -2 and 1 = 1. However, (5, 3) not_equal (3, 5) because even though they have the same components, 3 and 5, the component do not occur in the same order. Contrast this with sets, where {5, 3} = {3, 5}.
