$LaTeX:Symbols$

From AoPSWiki This article will provide a short list of commonly used LaTeX symbols. Operators Relations Negations of many of these relations can be formed by just putting \not before the symbol, or by slipping an n between the \ and the word. To use other relations not listed here, such as =, >, and <, in LaTeX, you may just use the symbols on your keyboard. Greek Letters Headline text Arrows (For those of you who hate typing long strings of letters, \iff and \implies can be used in place of \Longleftrightarrow and \Longrightarrow respectively.) Dots Accents When applying accents to i and j, you can use \imath and \jmath to keep the dots from interfering with the accents: \tilde and \hat have wide versions that allow you to accent an expression: Others Command Symbols Some symbols are used in commands so they need to be treated in a special way. (Warning: Using \$ for will result in . European Language Symbols Bracketing Symbols (\frac{a}{x} )^2 the parentheses don't come out the right size: gives Examples

Examples is generated by \[\sum_{i=1}^{n}\] is generated by \[\sum_{i=3}^{11}x^2\] is generated by \[\prod_{x\in(x)}\cos x^2\] -- note \cos rather than cos so LaTeX knows it's a function, and doesn't italicize it. is generated by \[ \lim_{x\to\infty} \int_0^{4{\pi}} \binom{n+m}{n-m} \sqrt[3]{\frac{2 + \cos x}{2 - \sin x}} dx \] note the optional [3] to make the cube root note: \limsup, \liminf, \sup, \inf work the same as \lim, changing only the word(s) displayed. is generated by \[\mathbb{R\quad Q\quad Z}\] blackboard bold font for reals, rationals, integers \[ \left|\sum_{i=1}^n a_ib_i\right| \le \left(\sum_{i=1}^n a_i^2\right)^\frac{1}{2} \left(\sum_{i=1}^n b_i^2\right)^\frac{1}{2} \] is generated by \[ H(x)=\left\{\begin{array}{cl} 0, & x<0 \\ 1, & x\geq 0 \end{array}\right. \] Internet references
