# fast_tri
> A blazing fast, branchless trigonometric library, it's header only
## Installation
To use `fast_tri` in your project, simply copy the `fast_tri.h` file into your project's directory and include it as follows:
```cpp
#include "fast_tri.h"
```
## Usage
This library only contains two functions:
* `double fast_sin(double)`
* `double fast_cos(double)`
> [!WARNING]
> The functions above can only handle inputs between 0 - 2pi !!!
## Benchmark
```
