Technically speaking the "proper" way to do it is use \mbox{}, like so:

$\forall \epsilon > 0 \, \exists \,\delta > 0 \mbox{ such that } |x-c| < \delta \Rightarrow \left| \frac{f(x)-f©}{x-c} - f'© \right| < \epsilon$

(that's the definition of differentiability at a point c)

Just going to test the code:

$e^{j\pi} + 1 = 0$

Sweet, thanks dave! This'll make things a little easier ;)
By the way, I had no idea that:

$\int_{-\infty}^{\infty}e^{-x^2} = \sqrt{\pi}$

I'll have to remember that. :)

Don't think it works because it's too long; I put a max character limit to stop people typing loads of stuff in and getting a stupidly large image for security purposes.

(btw I think I needed to add a dx to that integral)

(p.s. use i :D)

Mix maths and text to give this:

Let $\{v_1,v_2,...,v_k\}$ be the basis set for the vector space V which are linearly independent, then it is possible to construct another basis set $\{e_1,e_2,...,e_k\}$ from the original basis set, such that the basis vectors in the new basis set are all orthogonal to each other, i.e. $<e_i,e_j>=0$ for $i \neq j$ where $<,>$ is the inner product defined on the Vector Space V

That looks fine to me. Don't forget you need to put \ before { and } to tell [LaTeX Error: Syntax error] that you really mean those. If dave could put a math button to insert [ math] and [ /math] tags then it will be even easier to type.

Was thinking of writing a little math toolbar thing so that you can just click on the math symbols and the latex code would be inserted into the textbox.

I've also got a copy of the latest latexrender code, so I'll post that off to you soon with some instructions blike. I've managed to fix a few of the problems we have when quoting equations; the images produced are now transparent with a very minor reduction in quality from what we have atm, although it requires a little more CPU :-)

It is very useful in chemistry area

Read the initial post: subscripts are generated by using _

For example, A_{n^2} produces: $A_{n^2}$

Dear Dave

I have tried numerous times to use the latex code for Matrix and Align equations. When I use the command for matrix I get:

$\begin{matrix} w & x \\ annoyed & z \end{matrix}$

and for align:

[LaTeX Error: Syntax error]

As you can see the ampersand persists. I have read a few 'latex' manuals and tried various code combinations. Could you or someone else be able to provide some information to overcome this problem.

The problem is that when you type the & into vB, it cleverly converts it into the html symbol for an ampersand; namely & which is why you're having problems. When I get back from holiday, I'll fix it; it's a fairly simple fix.

Thanks for highlighting the problem though.

Dear Dave

Thanks for the reply, I had a thought that might be the case.

Just thought I'd post this link http://www.ctan.org/.../symbols-a4.pdf. It's a relatively small, (approximately 2.3 MB) comprehensive set of symbol tables for [LaTeX Error: Syntax error] and some of its add ons.

The page I got it from is here: http://www.ctan.org/.../symbols-a4.pdf.
