Tex and templates tricks
Take a look at this code:

$$a,b,c$$ and $$a',b',c'$$

$$a,b,c$$ and $$a',b',c'$$

To force png rendering, add \,\! into the formulas:

$$a,b,c\,\!$$ and $$a',b',c'\,\!$$

$$a,b,c\,\!$$ and $$a',b',c'\,\!$$

But... how to space a little more formulas and text? If you add text spaces or \quad spacing at the beginning or at the end of the formula it will not run:

$$a,b,c\,\!\quad$$      and      $$\quad a',b',c'\,\!$$

$$a,b,c\,\!\quad$$      and      $$\quad a',b',c'\,\!$$

But... this trick runs ;-)

$$a,b,c\, {\color{White}space}$$ and $${\color{White}Hi_people} a',b',c'\,\!$$

Take a look to the code. Obvioulsy space is only a "filler string of any desired lenght".... you are simply writing white letters over a white background --Alex brollo 11:01, 6 July 2008 (UTC)

Multiple intergrals and fine spacing
Take a look here:

$$\int\int R cos \epsilon dS = \int \int \int \frac{dX}{dx}+\frac{dY}{dy}+\frac{dZ}{dz} dx dy dz$$

Then here:

$$\iint R\,cos \epsilon\,dS = \iiint \frac{dX}{dx}+\frac{dY}{dy}+\frac{dZ}{dz}\,dx\,dy\,dz$$

Isn't the second one better? Take a look to the code: it uses \iint and \iiint TeX tags for multiple integrals and \, code for fine spacing. --Alex brollo 15:23, 6 July 2008 (UTC)

Other TeX tricks

 * Character & can be obtained with $$\And$$ : $$\And$$. I added the documentation into Help:Mathematics_and_Wikisource:_fractions_and_functions, it was lacking.
 * Trigonometric functions should be written so: $$\cos \alpha$$, with this result: $$\cos \alpha$$. This code gives a wrong result: $$cos \alpha$$ : $$cos \alpha$$
 * Spacing with TeX code \, gives a good result but forces png conversion of the formula: this code, $$dx\,dy\,dz$$ gives this result: $$dx\,dy\,dz$$

complement?
On Page:A Treatise on Electricity and Magnetism - Volume 1.djvu/57, it was using $$Q_1$$ instead of $$Q^'$$. I presume this is representing a complement of some sort. I've not sure what it the most appropriate way of transcribing this. John Vandenberg (chat) 10:29, 23 July 2008 (UTC)

Section titles
I note in places these are NOT appearing? How do I fix this? Sfan00 IMG 12:26, 12 August 2008 (UTC)
