Angle between vectors in 3D solver with steps calculates a vector geometry in 3-dimensions running from point A (tail) to point B (head). Each vector has a magnitude (or length) and direction and can be calculated by taking the square root of the sum of each components in space.

### How The Angle Between 3 Vectors Calculator Works

#### Using The Calculator

• Enter the values of each vector assuming you are working with vectors in this form

• Enter the corresponding values for each and
• Hit the equal orange button to generate the worksheet.

#### Inside the Calculator’s Brain

• Calculate the angle between 2 vectors in a 2d space using the formula

• Determine the dot product of the two given vectors

• Find the magnitude of the vectors

• Apply the formula by substituting the dot product and magnitude of the vectors where applicable

• Simplify the expression and find the acos of the result

• Express the final result in radians or degree,

### Vectors

#### What are vectors?

Vectors are quantities defined by magnitude and direction. The geometrical representation of a vector is by means of an arrow whose length, to some scale, represents the magnitude of the physical quantity and whose direction indicates the direction of the vector.

#### What is scalar?

A scalar quantity is one which is completely defined by its magnitude. To distinguish the magnitude of a vector a from its direction we use the mathematical notation

#### Magnitude of a Vector

If the components of a vector in a rectangular coordinate system are known. To distinguish the magnitude of a vector a from its direction we use the mathematical notation. Since the vector and its components form a right-angled triangle, we have the magnitude of a vector defined as

where  r = magnitude or modulus of Z and is written as mod Z or |z|. Note the actual value of r is determined by using Pythagoras’ theorem

#### Argument of a Vector, θ

The θ is called the argument (or amplitude) of Z and is written as arg Z. By trigonometry on triangle, argument or amplitude of Z is derived from the division of imaginary path by real path on y and x axis respectively
