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.

(see math.stackexchange.com/questions/149303/…). Though it's quite exotic format nowadays. $\endgroup$
