Learn How to Easily Insert Images on LaTeX | Helpful Tips and Tricks

[Juggler123]

Hi,
I know this isn't a general math problem but I didn't really know where else to post.
I'm trying to insert an image into a text I'm wrtting on LaTeX, the file is saved in .gif format in My Documents. I've read a little on the web about how I should insert the image into my text but I can't really make sense of it! Any help would be really great.
Thanks.

First off, you are going to need to convert that .gif file into a form that your LaTeX engine understands: .pdf, .png, or .jpg (assuming you are using pdflatex as your engine). Copy the converted file to your document directory, aka folder. (You can also place it in subdirectory of your document directory.) I'm going to assume you named it imagefile.png. Substitute accordingly for your file name. Add a \usepackage{graphicx} directive to the header of your .tex file and a \includegraphics{imagefile} in the appropriate place of the body of your .tex file, and voila! there is your image in your pdf file.

It is almost certainly better to make your graphics figures (floats). Read up on how to place figures in your LaTeX file.

Got another problem now,
I'm trying to type a double integral into my work but it keeps coming up with an error message.

\begin{equation}
M(x)=\iint y\cdot\sigma(x,y) dy dz
\end{equation}

To me this looks right!? I don't understand what is going wrong.
Any help would be great!

The command is cdots, not cdot.

 

[Juggler123]

Tried that but I keep getting the same error message...

 

[D H]

Works for me:

$$M(x)=\iint y\cdots\sigma(x,y) dy dz$$So what is the error message?

 

[LCKurtz]

cdot is a legit command and perhaps what the OP wants. It works on this board:

$$\begin{equation}<br /> M(x)=\iint y\cdot\sigma(x,y) dy dz<br /> \end{equation}$$

On this board maybe he forgot the tex tags.

Thank you for this thread, I have been wanting do just this for some while.

 

[Juggler123]

LCKurtz; that's exactly what I want but even when I copy and paste the formula into my work it still comes up with this error meassge;

[2]
! Undefined control sequence.
l.80 M(x)=\iint
y\cdot\sigma(x,y) dy dz
?

This is starting to get annoying now! I just can't figure it out...

 

[D H]

That complaint is about iint, not cdot. iint is not part of the base LaTeX set of macros. It is defined in the amsmath package.

Add \usepackage{amsmath} to your prologue.

Brilliant! Thankyou

After surrounding the corrected equation with tex tags, here's how it looks:
$$\begin{equation}<br /> M(x)=\iint y \cdot \sigma(x,y) dy dz<br /> \end{equation}$$

Edit: Didn't realize that I was restating what LCKurtz already said.
