Standard Function Names

Function names should appear in Roman, not Italic, e.g., arccos cos csc exp ker lim sup min sinh

arcsin cosh deg gcd lg ln Pr sup

\arcsin \cosh \deg \gcd \lg \ln \Pr \sup

Correct: Incorrect: arctan cot det hom lim log sec tan

\tan(at-n\pi) −→ tan(at − nπ) tan(at-n\pi) −→ tan(at − nπ)

\arctan \cot \det \hom \lim \log \sec \tan

arg coth dim inf lim inf max sin tanh

\arg \coth \dim \inf \liminf \max \sin \tanh

Array environment, examples

Simplest version: \begin{array}{cols} row1 \\ row2 \\ . . . rowm \end{array} where cols includes one character [lrc] for each column (with optional characters | inserted for vertical lines) and rowj includes character & a total of (n − 1) times to separate the n elements in the row. Examples: \left( \begin{array}{cc} 2\tau & 7\phi-frac5{12} \\ 3\psi & \frac{\pi}8 \end{array} \right) \left( \begin{array}{c} x \\ y \end{array} \right) \mbox{~and~} \left[ \begin{array}{cc|r} 3 & 4 & 5 \\ 1 & 3 & 729 \end{array} \right]



f(z) = \left\{ \begin{array}{rcl} \overline{\overline{z^2}+\cos z} & \mbox{for} & |z|<3 \\ 0 & \mbox{for} & 3\leq|z|\leq5 \\ \sin\overline{z} & \mbox{for} & |z|>5 \end{array}\right.
