## Introduction to Unit Vector Calculator:

Unit vector calculator is the best online source that helps you to **find the unit vector** of a given vector function. It is used to compute the vector function for normalization by dividing each term by its corresponding magnitude value.

The unit vector notation calculator is an educational tool that helps teachers, students, and parents teach their children about the concept of unit vector concept without sending them to any tutor by using its stepwise calculation method for finding the unit vector solution.

## What is Unit Vector?

Unit Vector is a type of vector that has a **magnitude of 1** as it indicates direction without specifying the magnitude of the original vector function. It simplifies the process of finding normalizing vectors of a vector function.

This method is used to find the direction of a vector without considering its magnitude because in a vector magnitude and direction are important components. It is used in fields like physics, engineering, and graphic design.

## Formula of Unit Vector:

The **formula of unit vectors** is used to normalize the vector function whose have a magnitude is 1 only for 2-D or 3-D space.

$$ u \;=\; \left( \frac{x}{||v||},\; \frac{y}{||v||} \right) $$

$$ u \;=\; \left( \frac{x}{||v||},\; \frac{y}{||v||},\; \frac{z}{||v||} \right) $$

Whereas,

||v|| = is the magnitude of function f(x,y,z)

u = unit vector direction of a function

## How to Calculate The Unit Vector?

To **calculate the unit vector** you need to know the vector quantities and its types so that you cannot confuse the direction and magnitude of a vector function. Here is the calculation process of calculating the unit vector function in steps.

**Step 1:**

Determine the unit vector function F(x,y) or F(x,y,z) in two-dimensional or three-dimension space respectively.

**Step 2:**

Find the magnitude of a given vector function using this formula for 3-D which is given as:

$$ ||v|| \;=\; \sqrt{x^2 + y^2 +z^2} $$

You can also modify the magnitude formula for two-dimension space.

**Step 3:**

After calculating the magnitude, use the below formula for the unit vector of a given function, in which divide each term by its magnitude to get a solution.

$$ u \;=\; \left( \frac{x}{||v||},\; \frac{y}{||v||},\; \frac{z}{||v||} \right) $$

**Step 4:**

Simplify it, if needed to simplify the unit vector of a given vector function.

## Solved Example of Unit Vector:

The **solved example** of a unit vector function gives you a better understanding about the conversion of unit vectors.

### Example: Find the unit vector in the direction of the vector

$$ v \;=\; (3, -4,12) $$

**Solution:**

The given vector function is,

$$ v \;=\; (3, -4, 12) $$

First, find the magnitude of a given vector using the below formula,

$$ ||v|| \;=\; \sqrt{x^2 + y^2 + z^2} $$

Add the value of above vector function as x = 3, y = -4, z = 12 to get magnitude value,

$$ || v || \;=\; \sqrt{3^2 + (-4)^2 + 12^2} $$

Simplify it,

$$ 9 + 16 + 144 \;=\; 169 $$

$$ ||v|| \;=\; \sqrt{169} \;=\; 13 $$

For unit vector divide each term of a function to its magnitude such as,

$$ u \;=\; \left( \frac{x}{||v||},\; \frac{y}{||v||},\; \frac{z}{||v||} \right) $$

Add the value to get the solution of the unit vector function in three dimensions,

$$ u \;=\; \left( \frac{3}{13},\; \frac{-4}{13},\; \frac{12}{13} \right) $$
