Learning to Math with LaTeX (1 Viewer)

[darkk_blu]

I'm learning to use LaTeX through MiKTeX and TeXMaker and can type most of the things I need but I want to be able to type on here using LaTeX for math stuff, it makes things easier to see and recommended by the forum. The text appears fine on the pdf preview but how can I copy and paste it over to here, or do I need to use snipping tool and insert/paste it as an image. Thanks.

Using LaTeX here (on BOS) is a bit different to using it on MiKTeX/TeXMaker etc. The biggest difference is that to use LaTeX here, you need to enclose the code within "TeX tags". These are like this: [tex.] <insert code here> [/tex.], except exclude those red full stops. (I only put the red full stops in because otherwise the tags don't display.)

Example: To produce , the required code on BOS is:

[tex[COLOR="#FF0000"].[/COLOR]] y = x^2 [/tex[COLOR="#FF0000"].[/COLOR]]

(again, exclude the red full stops).

If you want to write text in LaTeX here, you can use dollar signs ($) to help with that, but maybe just get used to typing mathematical expressions on BOS LaTeX first.

How can I do dy/dx or integral signs for BOS LaTeX? Is it ? How do i make it look "normal"?

How can I do dy/dx or integral signs for BOS LaTeX? Is it .

i.e. you write "\frac{a}{b}".

So to get dy/dx, the code is \frac{dy}{dx}.

For an integral sign:

[tex[COLOR="#FF0000"].[/COLOR]] [B]\int f(x) dx[/B] [/tex[COLOR="#FF0000"].[/COLOR]]

produces

.

(As usual, exclude the red full stops from the TeX tags.)

Also, you may find this site helpful: http://www.codecogs.com/latex/eqneditor.php . It lets you click buttons to obtain mathematical expressions, and then produces the LaTeX code for it for you.

Also, it might be useful to know these:

\sqrt{x} produces and \sqrt[n]{x} produces
_______________________________________________

For inequalities, you can use special commands:

\neq (not equal to)
\geq (greater than or equal to)
\leq (less than or equal to)
_______________________________________________

You can use \, to make an empty space.

x = 5, \, y = 2


_______________________________________________

You can use subscripts _ and superscripts ^ to add more information to commands, e.g.

\int^2_1



\lim_{x \to \infty}



_______________________________________________

You can use Greek symbols like this:

\theta (small)
\Theta (capital)
_______________________________________________

And finally all of the trig functions have their own commands

\sin

\sin^2

...

Same for other functions such as \log etc.

\displaystyle is my cheeky trick in LATEX for making fractions and integrals a bit more bitter if in a paragraph with $ $
here it doesn't matter sometimes
For example:

versus

I think they're just for using plaintext.
