The main reason that I stopped posting is that copy-pasting Latex equations from my files into WordPress produces the message “formula does not parse”. I have to manually retype the formula in the WordPress edit window, and then Preview gives the correct result. My formulas correctly work in all Latex processors, including TexShop, but they do not work in WordPress, unless I retype exactly the same formula.
Here is an examples:
This formula from my preexisting file,
\ddot x + \omega ^2 x + \lambda \,x (x^2 – y^2 ) = 0 ~~~\ddot y + \omega ^2 y + \lambda \,y (x^2 – y^2) =0 ,
I copied into WordPress, then I sandwiched it between “$latex” and “$”, and obtained the result:
When I retyped exactly the same formula, I obtained:
Etc., etc.: pasting formulas did not work, while retyping the same formulas did work.
Because I could not use my already existing Latex equations in WordPress, I was discouraged from producing new posts. It would have been too tedious to type all those equations again. Does anybody know how to copy latex equations into WordPress?
