## Angle between Vectors in 3D Calculator with Steps

**About The Calculator**

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.

**About Vector**

#### 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
