I have just looked through Dave's great tutorial on Latex and wonder if the original post could be altered in one small way to avoid confusion. I noticed this from Michel's point on the Stonehenge Mathematics.

 

Michel had, quite reasonably, looked at the Tutorial and I guess this line specifically

The images are clickable, so you can see the code that was used to make them by clicking.

 

He had wanted to get the symbol for pi. If you find an equation on the tutorial with pi - click and look at the code is appears as follows

 

[ math]int_{-infty}^{infty} e^{-x^2} = sqrt{pi}[ /math]

 

It has stripped out the backslashes

 

if you then try to put what the code shows you get

 

[ math] =sqrt{pi} [ /math] gives [math] =sqrt{pi} [/math]

 

rather than

[ math] =\sqrt{\pi} [ /math] gives [math] =\sqrt{\pi} [/math]

 

 

It would be useful to add a little line explaining that symbols need a preceding backslash that has been stripped out in the examples

I think Capn should simply fix the bug that eats the backslashes.
