# Math Help - LaTex Tutorial

1. ## LaTex Tutorial

Math Help Forum now Has LaTeX installed which allows a user to enter math equations into the forum. For example:

$\frac {x^2+5}{3x +1}$

To enter math equations you need wrap the equation with [ math] ...... [ /math] without the space between the [ m and the [ /

You can also click on the equation somebody else entered and see how it was done.

I will attatch a tutorial very soon
$= 2*1*4=$

2. Glad I could help :-)

As an example of what this can do, take a look at the Cauchy-Schwarz integral inequality:

$\left[ \int_a^b \phi_1(x) \phi_2(x) \, dx \right]^2 \leq \left( \int_a^b [ \phi_1(x) ]^2 \, dx \right) \left( \int_a^b [ \phi_2(x) ]^2 \, dx \right)$

3. ## Latex Instructions

Here are some tips for using Latex on this Forum:

Remember to wrap the equation with [ math] ......[ /math] without the space after the bracket [

4. ## thanks again for th advice

I was just makking my dad tyr to figure it out this morning

5. Question: Is the LaTex on this site the same as LaTex anywhere else? I've recently been discovering useful little commands (such as \in, \mathbb, etc.) that aren't in the list below. I was wondering if I could look them up on the general internet, or if there is a way to bring up a list of commands for the forum's version?

Thanks!

All of \in, \mathbb and \mathcal and other do work here, but not everything
I have tried has worked (but I forget what hasn't).

Looking them up elsewhere is how I find out about other commands, then
I experiment with them.

(Stealing other poster TeX also works for me)

7. As same as you tell everyone to learn Visual Basic or C++, to remember all this easily, i will do right away....Unfortunately, i am not.

my ideas just steal from others codes. That's might help. By the way anyone here know which website is good to learn Binary. Thanks

Unfortunately since the upgrade to this sites software (about a month ago)
the LaTeX system has not been restored, we are waiting with baited breath
for it to be reinstalled. Then you will be able to see answers to questions
in the full glory of elegantly typeset mathematical notation.

$\frac{3}{4}$

11. ## Celebrate!!!!!!!!!!!!!!!

sue me for smilie abuse

12. Posted the following two texts which didn't appear in LaTeX form,

1.
$$\frac{dy}{dx}(2x^2+6) = 4x[\math] 2. \documentclass{article} \begin{document} [tex]\frac{dy}{dx}(2x^2+6) = 4x[\math] \end{document} What's wrong? 13. 1) you don't need all those document class stuff and two, it's not [\math] it's$$

such as: $$\frac{dy}{dx}(2x^2+6) = 4x$$ makes $\frac{dy}{dx}(2x^2+6) = 4x$

14. Hm, I just can't find how to make the inequality sign... \(ó.ò)/

15. Hello, TriKri!

Hm, I just can't find how to make the inequality sign.

Use \neq . $\neq$
