I would like to write an article for a WP-site and include math equations. The site is hosted on own/rented servers (i.e. site is not a free or paid WP-blog).
The owners of the site are not technical and have no idea how to setup this but can follow simple instructions if needed. I have no admin rights on their server whatsoever and I do not want to have.
Firstly, I am looking to what choice there is out there for a way to do this in a free, open way which does not injects advertisement, places cookies on users, or monitors users across sites, or whatever other corporate practice which is not considered kosher for at least 99% of internet users.
For example, I would prefer that the processing-burden to be minimal, to use local cache for example (for the rendered images). But I would scream with horror on suggestions for 3rd-party servers to render and store said images and viewers of the article to load math-equation images from this 3rd-party server. That screams horror on its own.
Secondly, please include some instructions/links on how to set this up for non-technical people.
I have read of some options, like Jetpack, but it is still unclear to me about my first request: local cache, avoid 3rd-party servers, 3rd-party cookies and 3rd-party cross-site monitoring. Also, expressiveness and power, e.g. having microsoft equation quality is not what I am looking for. On the other hand LATEX will be the ultimate cure (WP+LATEX=L.F.E.)
Has anyone out there written the definite guide/comparison for math rendering options on WP-based sites?
P.S. it seems there are no appropriate SO tags for this post: e.g. mathematical-equations-rendering. Or something similar.
