Useful maths software

LaTeXiT

When you need to deliver a heavy payload of maths into a presentation, a figure, or a non-LaTeX document, then this tool is highly useful. LaTeXiT is a really nice, and free, piece of software for the mac that allows you to generate equations and import them into other documents in a whole bunch of formats. The really cool thing is that once imported, you can just double click and it opens up the equation to edit it.
