Experimenting with Latex
Ok, if this works then this should produce an equation: \right )}

ok, that doesn't look too bad. I wonder if I get complicated like with:} \end{cases}

Ok, I am impressed. That looks quite cool :)

Hello Kiwiheritic...

I have used MathType (15 years now). I need a Latex capability. I need it to use at PHF and I need it at my site. Please look at my site. The platform is html pages, driven via a php database. Might you be hired to advise me how to get some beginning equations up at PHF and on my pages?

Please visit my home page, follow links to the interior. See the scope of what I have.

Thank you, Jim Pohl (home page)

Thermo: as noted in other threads PHF does not have LaTeX capability. Use, and copy and paste it's output into your posts here on PHF. This same technique may work for your site as well as long as you allow embedded images.

To produce that output, in my initial post, I used a simple [ IMG ] tag insert as described here:

To generate the Latex code I used sympy. An online version can be found here:

After sympy generates the fancy styled equation I right click on it then select "Show Math as" and then "TeX commands" from the submenu. I then copy and paste that into PHF as per the first link.

So here's my test of that method:^2-4ac}} {2a}

Yep, works. Nice that you don't have to copy from texify, but you do have to memorize the secret command:

[img]*LaTeX commands go here*[/img]

I didn't use simpy - I simply placed the LaTeX commands as instructed - in this case: \frac {-b \pm \sqrt {b^2-4ac}}{2a}

$$[r cos \; 45-|\overline{BC}|cos \; a]\overline{I}+[|\overline{AB}|-r sin \; 45]\overline{J}+
[|\overline{BC}|sin \; a-r]\overline{K}=0$$

Yours is the way I would code it, but some others prefer the following:
$$[r \cos \; 45-|\overline{BC}| \cos \; a]\overline{I}+[|\overline{AB}|-r \sin \; 45]\overline{J}+
[|\overline{BC}| \sin \; a-r]\overline{K}=0$$

It's not much different, just use \sin and \cos.
