What command did you use to create your avatar on AoPs?

You can use \mathop{{\int\!\!\!\!\!\int}\mkern-21mu\bigcirc}{}

This yields

How can I insert an image in my post?
I used the "Insert image " button, but one ask me to introduce the URL and the image is in my own computer.

You can use ImageShack

It's the best way to upload & plug the images to the forum

I've never used Image Shack on this site. I always upload from my computer. Go to "manage attachments", then click on browse at "upload file from your computer". It's always worked great for me.

But I don't find "Manage attachments".

Really?. That's odd. It's there when I click "post reply". Scroll down to it. That doesn't make sense.

It's right beneath where you write your post. Under "Additional Options", "Attach Files". There's a icon bar that reads "Manage Attachmants".

Is it possible to create the command

Code:

\gal

To produce .
Instead of writing,

Code:

\mbox{Gal}

And hence saving time?

I have more such commands which I end up using. So if it possible I can create a list.

I think it's possible to set a command like that.

You can also write in text using \text

Not hard.

P.S.: or for some special commands, using \mathrm

Is Texnic Center good for writing LaTeX files?

Yeah, good software

The standard LaTeX method of creating commands does not work.

Code:

\newcommand{\gal}{\ensuremath{\mbox{Gal}}}
\gal

Can someone please give me the code for:

1. 3^(3x +4).18^(-x-2)/24^(x+3).4^(-2x-1)



2. 21^(3x+1).7(2-x)/49^(x-1).27^(x-4)

Thanks in advance.

Thanks in advance.

3^(3x +4).18^(-x-2)/24^(x+3).4^(-2x-1)



which is generated by:


[tex]\frac{3^{3x +4}.18^{-x-2}}{24^{x+3}.4^{-2x-1}}[/tex]


21^(3x+1).7(2-x)/49^(x-1).27^(x-4)



which is generated by:


[tex]\frac{21^{3x+1}.7^{2-x}}{49^{x-1}.27^{x-4}}[/tex]

Thanks a million.
