I want know if there is a better way to post equations compared to the existing?
What would you find a "better way"? If you find using ##\LaTeX## cumbersome, I can understand that it requires a bit of getting used to, but I can assure you that it is very much worthwhile, not only for your time here. There is a primer on it, too.
Yeah, if you can tell us a better way to do equations than LaTeX, or a "visual" LaTeX editor, that can be integrated into Xenforo forum software, please do!
There is one better way and that is to prepare equations , diagrams , text and final layout using personal software and then paste or upload result into PF .
I use CAD but there is lots of other software available for this purpose .
Setting out even very complicated equations in clear format is easy in CAD because it is done graphically - you just move things around with the mouse until layout is perfect . Many fonts including scientific symbols are available but if anything special is needed you just create it and add to your personal graphic symbols library .
One of the reasons why I like ##\LaTeX## is because I do not have to move things around to optimize the layout - the typesetter does it for me.
Out of curiosity: Can one also use ##\LaTeX## strings in typical CAD packages?
Not that I know of . Could be done though if facility was ever needed - most modern CAD systems allow user written routines to be added .
This has one major problem: people replying to a post can't quote individual equations out of an image, or edit them to show corrections.
Ops! I'm sorry, but I did not realize that you could also use latex! Now I will!
