In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi MIF

It seems the plus problem is very persistent: http://www.mathisfunforum.com/viewtopic … 26#p253826

Re: plus signs in Latex

To speed up page loads, once latex is created it is kept in a large cache. If latex was always being created things would be really slow.

So if you write some latex that has already been done you get that old version.

Try changing it a little (say with a space or variable change) and it will likely have to make a new one that works properly.

Re: plus signs in Latex

So, the cache has the LaTeX version of that expression from before you fixed the plus problem?

Re: plus signs in Latex

Yes, and I can delete it manually, by looking up its cached name. Such as "f/f/29156445d5e534d194b44703db36ab1.gif" for the misbehaved image above.

LaTeX is not parsing the character ' at the moment. neutral

A workaround would be to escape it:
