# Math Component
[](https://components.espressif.com/components/espp/math)
The `math` component provides various classes and static functions for commonly
used math operations.

## Bezier
The `bezier` header provides a templated implementation of cubic bezier curves
and rational cubic bezier curves. Intended use for these templated functions is
on raw floating point values or on the associated Vector2d class.
## Fast Math
The `Fast Math` header provides a set of static functions which implement
optimized approximations of the following functions:
* fast_sqrt
* fast_ln
* fast_sin
* fast_cos
along with some utility functions:
* square (x^2)
* cube (x^3)
* sgn (sign of a number)
* round (round floating point value to nearest integer value)
* lerp (linear interpolate between two points)
* inv_lerp (inverse linear interpolate between two points)
* piecewise_linear (compute the piecewise linear interpolation between a set of points)
## Gaussian
The `gaussian` class provides an implementation of the gaussian function:
```math
y(t)= \alpha e^{ -\frac{ (t-\beta)^2 }{ 2\gamma^2 } }
```
The class allows for dynamically changing the $\alpha$, $\beta$, and $\gamma$
parameters.
## Range Mapper
The `RangeMapper` provides a class which allows you to map from a configurable
input range to a standardized output range of [-1,1].
## Vector2d (2 Dimensional Vector)
The `Vector2d` provides a container for a 2-dimensional vector with associated
math operations implemented.
## Example
The [example](./example) showcases some of the math functionality provided by
the `math` component.
