LATEX guide Alden Gassert September Cii CContents An introduction to LATEX Resources Modes Environments Document Homework de ?nitions theorems and proof Lists Displayed equations Labels links and references Fonts Text fonts Math fonts Text in math mode Key words Symbols Algebraic expressions Algebraic relations Braces Brackets Parentheses etc Dots Functional notation Greek alphabet Large symbols Logical symbols Quotation marks Set notation Special symbols Color Colored text and text boxes Mixing colors iii Civ CONTENTS CChapter An introduction to LATEX Resources In this course all written work must be done in LATEX Software for composing LATEX documents is freely available online and there are also a number of free-to- use websites for creating collaborative LATEX documents useful for group assignments Links LATEX wikibook All things LATEX http en wikibooks org wiki LaTeX ShareLaTeX Collaborative tex documents https www sharelatex com Overleaf Another website for collaborative tex-ing https www overleaf com Detexify Looking for a symbol but you do not know what it is called Look up a symbol by drawing it Tends to be hit-or-miss but still generally useful http detexify kirelabs org classify html Symbols list More than you will ever need ever http www tex ac uk tex-archive info symbols comprehensive symbols-a pdf TikZ You might learn how to draw pictures one day http www texample net tikz examples Acquiring LATEX If you are interested in obtaining LATEX for personal use http latex-project org ftp html Writing with good practices A reference http www math illinois edu dwest grammar html C CHAPTER AN INTRODUCTION TO LATEX Modes There are two primary modes in which LATEX is written text mode and math mode Text mode is used for text write as you would in any word processor Anything mathematical should be written in math mode A dollar sign is used to transition between the two modes Input A function f colon A to bbr is emph continuous if for each epsilon there exists a delta such that if x-c delta then f x - f c epsilon Output A function f A ? R is continuous if for each there exists a ? such that if x ?? c ? then f x ?? f c Math mode has two styles math can be written in-line as in the example above using dollar signs or it sectioned away from text and be displayed Some symbols will be type-set di ?erently depending on the style You can force displayed math to appear in-line using the command displaystyle or ds ?? in math mode However if you are going to write display-style math you might as well place it in the align environment see the next section Input In-line math lim x to infty int x frac x dx and forced displaystyle in-line ds lim x to infty int x frac x dx Output In-line math limx ? ? x x dx and forced displaystyle in-line lim x ? ? x dx x Environments In short an environment is simply a set
