OK, I see your point. I guess it's now time for the decision makers to consider whether it will be worth the effort. I did what I could to advertise the idea and its utility, and now I can only cross my fingers

Thanks for the time and consideration so far!

Jefito - and then you need to multiply your list by the number of supported platforms.....

No problem -- thanks for making the suggestion and presenting it well.

yes ! It is a very nice suggestion.

I think there're many people want evernote can use Latex, it is extremely useful for students and scientists.

I hope this will come true in future.

Thanks for the suggestion.
Things like this are a little more complicated in Evernote because we store note data in a form of HTML that is then "rendered" for viewing separately on every platform: web (4 different browsers), mac, windows, iOS, Android, BlackBerry, Palm WebOS, WinPhone7, etc...

So any little tricky special syntax that we add needs to have corresponding rendering code added to every single client, or else we'll receive anger from the users of each platform because we (e.g.) failed to add LaTeX support on BlackBerry, so their notes are unreadable.

This is why we tend to prefer using existing web-friendly renderings like JPEG, GIF, PDF, etc. rather than ad-hoc markup within the notes for each separate community and feature.

+1 for latex .. Nerds lives will be much simpler with it

As for implementing it, wordpress already has done it and it renders on all platforms! The disambiguation is solved by using a slightly complicated (but usable) tag: $latex \alpha^2=\gamma$

I would also love this to see this feature. Without it Evernote is hardly usable for my work.
I'm surprised that MathJax hasn't been mentioned yet: www.mathjax.org

+1 For Latex Support!!!!

Also: Could we also add support for the following!? i.e. code snippet formatting?

for(int i=0;i++){

cout<<"+1 For Latex Support"<<endl;

else {mNTimesIgnoredBecasueImAGeek == i;}

}

cout << "Thanks for the Latex Support!!!"

The new Evernote Peek iPad app seems like it would be a fun and useful way to study. However, does Evernote provide any way for students of physics, chemistry, mathematics, engineering, computer science, &c. to typeset the formulas they are studying? LaTeX via something like MathJax would fit the bill, as it is standardized, commonly used, and encodes content for all those disciplines.

A similar web-based flash card study app Anki (http://ankisrs.net/shots.html) has support for LaTeX.

With the iPad study app, Evernote seems to be trying to attract students who will become knowledge workers and will depend on something like Evernote to manage their information.

Erm... Syntax error, line 1: expected ';' before ')'

Maybe you need syntax checking too...

LaTeX and/or MathML would be killer in evernote. Most hardcore math users (scientists, students, teachers...) would probably opt for LaTeX because the expressions are much (MUCH) shorter than MathML, but one could argue either way. But having math, real math in notes is central to people who use math.

As for implementation, don't reinvent the wheel. Check out mathjax (http://www.mathjax.org/). Open source. JavaScript. Handles LaTeX or MathML and interprets it to html for webservers. Even available as a WordPress plugin. The heavy lifting is done. You run it on your server, it reads the math codes between your delimiters, it spits back inline images of the math. Loverly. You can leave the actual creation of the codes to the user. If they are sophisticated users, they just type in the codes as they go. If they are writing complex expressions with unfamiliar math or are more casual users they use any of the many good button oriented editors available free or for fair fees. Or dump the codes out of their favorite math programs.

Could happen. Really could...

Getting off my soapbox now. Thanks for listening.

As just a modern university student, I think this is a must for students. It is entirely too difficult to substitute mathematics notes and if you want to be taken as a serious note taking application, having some kind of mathematics capability is a must.

Thanks and I really hope you decide to implement this. It would be IMMENSELY useful.

I won't make any arguments for whether implementing this would be easy or not, but I will say that I would love it if it was. I need equations a lot and usually have to use either Google docs or *gasp!* Microsoft Word to make them. Having LaTeX equations would make Evernote more of an all in one note taking application.

I found a way to display MathJax in an EverNote note -- but the trick is to display it in WordPress. WordPress has plugins for both EverNote (plugin is called EverPress) and MathJax. Set the EverPress plugin to link to a shared notebook in your EverNote account (and whatever other settings you want for displaying notes). When you want to include some MathJax in a note, you need to double-escape the LaTeX commands -- so, for example, instead of "$$\int e^x\, dx=e^x+C$$" in your note, write it as "\$$\\int e^x\\, dx=e^x+C\$$". Then when the note displays in WordPress (with the MathJax plugin), the LaTeX will be correctly typeset in the WordPress page. Until someone finds a way to get the EverNote site to actually use MathJax, this looks like the best option available.

BTW -- even though I found a workaround (above) for getting MathJax to display in an EverNote note via the WordPress plugin, this doesn't really answer the problem of getting math to display in a note on the EverNote site. I agree with previous comments that MathJax is probably the easiest way to implement this. This can't be done by a normal EverNote user because ENML doesn't support a

There is another workaround available for getting math into an EverNote note: Google Infographics math formulas -- see the page at this link:

This option has a lot of disadvantages, though -- between the potential server latency issues of dealing with the Google servers and the massive inconvenience of URL-encoding the TeX expression, it's just a pain to use. But since ENML does support the tag, it works. The Google charts server processes the TeX into a PNG image, which is included in the note with the tag.

I still vote for MathJax installed on the EverNote server -- I'm just trying to give options until that happens.

LaTeX is the language of choice for physicists, mathematicians, many engineers and economists. The original language was written by Donald Knuth and has remained the top choice for mathematical typesetting for close to 30 years.

Is there something about Evernote versus Wordpress that gives Wordpress a better ability to do this?

As a PhD student, Latex support in Evernote would make it a fully capable lab research notebook for me, whereas now I only use it for simple web clipping. I really hope the evernote team takes a serious look at this
