You can quickly create LaTeX documents online in a ShareLaTeX account. (By the way, you can optionally use your Google credentials to open such an account which is very convenient!). Personal accounts, with up to one collaborator, are free. This system has everything installed and ready to go, just log in and type away to create a document and compile it into a PDF.
If you use LaTeX on a regular basis then we recommend installing it onto your computer.
- First, get a TeX typesetting system (they are free):
- Pick an editor. Any text editor would do, but some have nice dedicated features such as syntax highlighting, and shortcuts to automatically typeset your documents. Here are some more beginner-friendly ones:
- Keep a reference handy. For instance LateX Wiki, or this LaTeX cheat sheet.
- Here is an introductory page from TeX Users Group. It has links to many resources and tutorials including Spoken video tutorial on LaTeX
- Not so short intro to LaTeX is, indeed, not excessively short, but overall very concise and one of the best references available. If you wish to immediately get to basic examples, then start at section 1.3 "Latex Input Files".
- A sample LaTeX homework template to start playing with.
- Here is a more advanced template showcasing among other things multi-line formulas and matrices.
- A sample Beamer file (LaTeX framework for presentations).
- Detexify is a search engine for (La)TeX symbols. Just sketch a symbol on the screen with a mouse, and the site will look up the corresponding LaTeX command for you. Note that some special characters require additional packages to be loaded by your document.
