Question

express the unit vector a cab in mathematical form
​

Answer 1

Step-by-step explanation:

In mathematics, unit vector refers to the normal vector space (often a spatial vector) of length 1. Moreover, we use a lowercase letter with a circumflex, or ‘hat’ (Pronunciation “i-hat”). Usually, we use the term direction vector to describe a unit vector to represent the spatial vector. Besides, we denote them as d. Moreover, 2D spatial directions represent this way are numerically equivalent to the points on the unit circle.

Answer 2

Answer:

A unit vector is something that we use to have both direction and magnitude. Moreover, it denotes direction and uses a 2-D (2 dimensional) vector because it is easier to understand. In addition, we can plot it on a graph. Besides, in this topic, we will discuss unit vector and unit vector formula, its derivation and solved examples.
