[Math] free software to create equations and export to various formats

Question

I'm looking for free software to create equations, and then be able to export to formats such as .jpg, .pdf, or maybe even MathML.

Open source is nice but not required, internet based would be great but a local installed application would work as well.

Being able to create graphs would be a positive, but I know of decent software for that so that's not a requirement.

I have used the equation creator and Word and that is workable, but not free and easy to distribute.

The choice of tool is very dependent on what you are going to use it for. If you are going to include the equation in an e-mail for example, use an online tool to produce an image.

If the equation is for an article/report, then you should not use an online tool, but rather the build-in tools in Word (maybe look at MathType) or $\LaTeX$.

Examples of online tools who all use the $\LaTeX$-syntax are:

• Tex2Img: http://www.sciweavers.org/free-online-latex-equation-editor
  • Exports to: PNG, GIF, JPG, TIF, BMP, PNM, FIG, PS
• Codecogs Equation Editor: http://www.codecogs.com/latex/eqneditor.php
  • Exports to: GIF, PNG, PDF, SWF, EMF, SVG
• Texify Equation Editor: http://www.texify.com/
  • Exports to: GIF
• Roger's Online Equation Editor: http://rogercortesi.com/eqn/
  • Exports to: PNG, JPG, TIF, GIF
• TeXRendr: http://www.texrendr.com/
  • Exports to: PNG

Edit: I have just discovered this page, which lists a lot of MathML editors.
