Use $$and$$ tags NOT $and$ tags for latex.

This is due to some technical issues recently experienced by MHF.

Thanks for taking the initiative to make this thread. I think I will make a forum wide announcement regarding this.

EDIT: Forum-wide announcement has been made.

Might also be useful to mention that the  environment doesn't like "returns" or "enters" or "carriage returns" or "line feeds" in its code, unlike regular LaTeX. That's what gives you those annoying <br> symbols in the result. Example:

[TEX]
\int_{-\infty}^{\infty}e^{-x^{2}}\,dx=\sqrt{\pi}
[/TEX]

yields

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

But

[TEX]\int_{-\infty}^{\infty}e^{-x^{2}}\,dx=\sqrt{\pi}[/TEX] yields

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

I just noticed that in one of the posts made here: http://www.mathhelpforum.com/math-he...ms-180257.html

It may have to do with the way it is interpreted by the site that I'm using to power the $$brackets...I'll look into this soon. • December 2nd 2011, 12:37 PM maxgunn555 Re: Use [tex] and$$ tags NOT $and$ tags for latex.
$Let (X; dX) and (Y; dY ) be two\ metric\ spaces\ and\ f : X \rightarrow Y be\ a\ mapping. Then\ f \is\ continuous\ at\ a \epsilon\ X if\ and\ only\ if\ for\ every\ neighborhood\ V\ of\ f(a)\ there\ exists\ neighborhood\ U\ of\ a\ such\ that\ f(U)\subset  V\\ Prove\ this\ theorem$

Any attempts will be thanked.

how on earth do i make the maths notated part font larger? thnx.

What do you mean by "larger"?
Is this not large enough $\sum\limits_{k = 1}^{10} {x^k }~?$

Only put your equations in tex tags, not plain text.

Re: Use $$and$$ tags NOT $and$ tags for latex.
sorry but I can't see the difference in your title. Should it be $and$ NOT $$and [\tex]? • November 6th 2012, 04:45 PM hexrei Re: Use [tex] and$$ tags NOT $and$ tags for latex.

$3x^2+4ix+5<0$ , $i^2=-1$.

Another way:
$$3x^2 + 4ix + 5 < 0,~i^2 = -1$$

$3x^2 + 4ix + 5 < 0,~i^2 = -1$

Re: Use $$and$$ tags NOT $and$ tags for latex.
Just a reminder for those who already have MathType -- you can use it here on MHF, and it formats the math properly. We have instructions on our website describing how to do that.
