# Compilation of miscellaneous tools

Useful web tools I have found for maths. In descending order of how well known they are (approximately)

- Complex Mapping Visualizer: Visualising complex mappings (I’ve made a version of it that directly supports \(\mathbb{R}^2\) to \(\mathbb{R}^2\) mappings here)
- Field Play: Visualising vector fields
- Quiver: For drawing commutative diagrams
- Mathematical operators and symbols in Unicode: Finding symbols in Unicode (that you can use in “plain text”)
- Detexify: Finding symbols in \(\LaTeX\)
- Microsoft Paint Online Open-Source, Web Components-based remake of MS Paint using modern web capabilities

Thanks to Isaac Li for telling me about Field Play.
