Graphest


A graphing calculator that faithfully plots arbitrary mathematical relations.




  

  



## Getting Started

1. 📦 [Download the app](https://github.com/unageek/graphest/releases) available for both macOS and Windows.

2. 🎉 Copy and paste some of the [example relations](Examples.md), and voilà!

## Features

- Plots arbitrary equations/inequalities

- Never gives an incorrect result; if you find any relation plotted incorrectly, please [report it here](https://github.com/unageek/graphest/issues/new)

- Cartesian and polar coordinates

- Parametric relations

- Full interactivity

- Extensive set of [mathematical functions](https://unageek.github.io/graphest/guide/)

## [Building from Source](docs/build.md)

## Algorithm

Graphest aims to provide a modern, open-source and extensible alternative to [GrafEq™](http://www.peda.com/grafeq/) [Ped].

The following algorithms in [Tup01] are implemented: 1.1–3.2, 3.3 (partially), 3.4.1–3.4.3, 3.4.5 (partially).
