Question

what Is unit vector ........​

Answer 1

Answer:

Hope this answer helps you!

Explanation:

A unit vector is a vector of length 1, sometimes also called a direction vector (Jeffreys and Jeffreys 1988). The unit vector having the same direction as a given (nonzero) vector is defined by. where denotes the norm of , is the unit vector in the same direction as the (finite) vector .

Answer 2

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 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.
