# PolyGo

A collection of basic tools that make working with polynomials easier in Go.

## Installation

``````go get -u github.com/SeanJxie/polygo
``````

## Documentation

You can find the full list of functions through godoc: https://pkg.go.dev/github.com/SeanJxie/polygo

## Examples

• Create a simple quadratic and find the root:

```package main

import (
"fmt"
"github.com/SeanJxie/polygo"
)

func main() {

quad.PrintExpr() // 0.000000x^0 + 0.000000x^1 + 1.000000x^2
fmt.Printf("Root: %f\n", root) // Root: 0.000000
}```
• Create a polynomial and find the derivative:

```package main

import (
"github.com/SeanJxie/polygo"
)

func main() {
coeffs := []float64{5, 2, 5, 2, 63, 1, 2, 5, 1}
poly, _ := polygo.NewRealPolynomial(coeffs)
deriv := poly.Derivative()
poly.PrintExpr() // 5.000000x^0 + 2.000000x^1 + 5.000000x^2 + 2.000000x^3 + 63.000000x^4 + 1.000000x^5 + 2.000000x^6 + 5.000000x^7 + 1.000000x^8
deriv.PrintExpr() // 2.000000x^0 + 10.000000x^1 + 6.000000x^2 + 252.000000x^3 + 5.000000x^4 + 12.000000x^5 + 35.000000x^6 + 8.000000x^7
}```
