Answer:
Unit Vector
A vector is a quantity that has both magnitude, as well as direction. A vector that has a magnitude of 1 is a unit vector. It is also known as Direction Vector. Learn vectors in detail here.
For example, vector v = (1,3) is not a unit vector, because its magnitude is not equal to 1, i.e., |v| = √(12+32) ≠ 1. Any vector can become a unit vector by dividing it by the magnitude of the given vector
Unit Vector Symbol
Unit Vector is represented by the symbol ‘^’, which is called a cap or hat, such as: a^. It is given by a^=a|a|
Where |a| is for norm or magnitude of vector a.
It can be calculated using a Unit vector formula or by using a calculator.

Unit Vector in Three Dimension
Unit vectors are usually determined to form the base of a vector space. Every vector in the space can be expressed as a linear combination of unit vectors. The dot products of two unit vectors is a scalar quantity whereas the cross product of two arbitrary unit vectors results in third vector orthogonal to both of them.

What is the unit normal vector?
The normal vector is a vector which is perpendicular to the surface at a given point. It is also called “normal,” to a surface is a vector. When normals are estimated on closed surfaces, the normal pointing towards the interior of the surface and outward-pointing normal are usually discovered. The unit vector acquired by normalizing the normal vector is the unit normal vector, also known as the “unit normal.”Here, we divide a nonzero normal vector by its vector norm.
Unit Vector Formula
As explained above vectors have both magnitude (Value) and a direction. They are shown with an arrow a⃗ . a^ denotes a unit vector. If we want to change any vector in unit vector, divide it by the vector’s magnitude. Usually, xyz coordinates are used to write any vector.
It can be done in two ways:
a⃗ = (x, y, z) using the brackets.
a⃗ = xi^ + y j^ +z k^
Formula for magnitude of a vector is:
|a⃗ |=x2+y2+z2−−−−−−−−−−√
Unit Vector = VectorVector′smagnitude
The above is a unit vector formula.
How to find the unit vector?
To find a unit vector with the same direction as a given vector, we divide the vector by its magnitude. For example, consider a vector v = (1, 4) which has a magnitude of |v|. If we divide each component of vector v by |v| we will get the unit vector uv which is in the same direction as v.
