A quick guide to L A T E X What is L A T E X? L A T E X(usually pronounced “LAY teck,” sometimes “LAH teck,” and never “LAY tex”) is a mathematics typesetting program that is the standard for most professional mathematics writing. It is based on the typesetting program T E X created by Donald Knuth of Stanford University (his ﬁrst version appeared in 1978). Leslie Lamport was responsible for creating L A T E X a more user friendly version of T E X. A team of L A T E X programmers created the current version, L A T E X 2 ε . Math vs. text vs. functions In properly typeset mathematics variables appear in italics (e.g., f ( x ) = x 2 + 2 x - 3). The exception to this rule is predeﬁned functions (e.g., sin( x )). Thus it is important to always treat text, variables, and functions correctly. See the diﬀerence between x and x, -1 and - 1, and sin ( x ) and sin( x ). There are two ways to present a mathematical expression— inline or as an equation . Inline mathematical expressions Inline expressions occur in the middle of a sentence. To produce an inline expression, place the math expression between dollar signs ( $). For example, typing$90^{\circ}$is the same as$\frac{\pi}{2}$radians yields 90 is the same as π 2 radians. Equations Equations are mathematical expressions that are given their own line and are centered on the page. These are usually used for important equations that deserve to be showcased on their own line or for large equations that cannot ﬁt inline. To produce an inline expression, place the mathematical expression between the symbols $and$ . Typing $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ yields x = - b ± b 2 - 4 ac 2 a . Displaystyle To get full-sized inline mathematical expressions use \displaystyle . Use this sparingly. Typing I want this$\displaystyle \sum_{n=1}^{\infty} \frac{1}{n}$, not this$\sum_{n=1}^{\infty}\frac{1}{n}\$. yields I want this
