Re: LaTeX - A Crash Course

Hi loida;

We cannot use packages in this latex.

Is that essentially the same symbol?

That is what I thought. How did you get the answer then?

Re: LaTeX - A Crash Course

Hi, yeah, I won't go into the details, but basically LaTeX is a mark-up language, and they way mark-up works - as you will probably have realised - is that if you want your text to appear in a certain way - such as to be in bold face - then you 'mark up' the text. i.e. you use special sequences of characters (called control sequences) to induce an effect (e.g. \textbf{Hi} makes Hi become Hi. textbf is the control sequence and the \ is known as the escape character, which escapes the control sequence. This means that the control sequence is interpreted as a command, rather than just normal text.) Anyway, I probably could have explained that better, but it's not very important, so don't worry if you didn't follow it. The main point is that these control sequences are interpreted by a renderer, which creates the final document. Now, the renderer already 'knows' the basic commands, such as \frac{x}{y}, however, we can also write packages which extend LaTeX beyond these very basic functions. Now, bbold is an example of a package which was written to give LaTeX more functionality. If our renderer doesn't know how to interpret \mathbb{1} in the way we want it to, then we have to load that package, and then the renderer will use the information contained in that package to interpret our control sequence. Otherwise, it will use the standard interpretation. IIn this case, the mathsisfun renderer does know the standard interpretation (bobbym's symbol) but not the interpretation you want. If you ever use your own renderer and write LaTeX for yourself outside of this forum, then you can use the bbold package and extend your own LaTeX capabilities. However, the mathsisfun forum (for very good reasons, mostly simplicity but also to prevent abuse) does not support the loading of extra packages, so we have to make do with the functionality we have.

Re: LaTeX - A Crash Course

Hi smile

Is that on the forums or at home? On the forums, you cannot insert any pictures in LaTeX, you must use the standard bbcode. At home, if you are using graphicx, the supported image formats really depend on the renderer which you are using, however, I do not know of any renderer which supports .gif. pdflatex - the most common and, indeed, useful one, will only support .jpg, .png and .pdf, to the best of my knowledge. It may have expanded its abilities by now, or there may be a package which can do something clever and allow .gif files to be inserted (almost certainly by converting them to .jpg/.png for you) but I think that this is quite unlikely. Instead you should use one of these formats. Indeed, if you are using it for a diagram, then a vector image in .pdf format will definitely have a much much better effect.

Re: LaTeX - A Crash Course

Hi Ioida smile

In your preamble write

\usepackage{graphicx}

Graphicx will probably look for the picture in whichever directory the .tex file is in, but it's best to specify the graphicspath - especially if your picture is somewhere else on the system, in which case it won't find it, so write underneath that (yes, two braces, it works better, apparently):

\graphicspath{{filepath}}

Then, wherever you want the picture:

\includegraphics{filename}

It should not be necessary to include the extension. You can also scale the picture using

\includegraphics[scale=x]{filename}

Give x as a decimal, e.g. 0.5 or 1.8.

You can also use the figure environment if you want captions. There is a lot of information about this in the LaTeX manual (http://en.wikibooks.org/wiki/LaTeX). There are also dedicated forums for LaTeX queries, and - indeed - TeX queries in general, and I suggest that for general TeX questions you go there. Not that I'm not completely happy to help, but you're much more likely to find your answer. Also, please remember that this won't work for .gif, I don't think. You should be using .jpg, .png or .pdf.

Re: LaTeX - A Crash Course

Hello hi2

Welcome to the forum!

What is cool? LaTeX? I agree.It is a very powerful tool for helping someone understand mathematics.

Do you know how to use LaTeX?
