PHP-Math-Vector
===============

[](#php-math-vector)

A math library for handling vectors.

1. Features
-----------

[](#1-features)

`PHP-Math-Vector` handles 2-dimensional vectors and 3-dimensional vectors.

`PHP-Math-Vector` can:

- return the length (magnitude) of the vector
- return the unit vector
- return a vector multiplied by a real number
- add two vectors
- subtract one vector from another
- return the `dot product` of the two vectors
- return the `cross product` of the two vectors
- return the `cosine` of the angle between two vectors
- return the angle between two vectors in `degrees` or `radian`
- return the `initial point` or `terminal point`
- return a set of each component of x and y
- rotate the vector by a specified angle

5. Usage
--------

[](#5-usage)

### 5.1. Two-dimensional Vectors

[](#51-two-dimensional-vectors)

To handle two-dimensional vectors, create instances of `Vector2d` class at first.

#### 5.1.1. Instantiation

[](#511-instantiation)

`Vector2d` class needs `initialPoint` and `components` as arguments.
