About the test scope

Syntax#

\begin{align*}…math body\end{align*}

Takes no arguments. Reading argspecs

Common tasks#

How to align equations without numbers#

\begin{align*} a &= b+c \\ &= d \end{align*}

How to write an unnumbered system#

\begin{align*} x+y &= 1 \\ x-y &= 0 \end{align*}

How to suppress numbering on a derivation#

align* is the unnumbered sibling of align; \nonumber also works inside align.

\begin{align*} f'(x) &= \lim_{h\to 0}\frac{f(x+h)-f(x)}{h} \\ &= 2x \end{align*}

In TeXForm#

TeXForm reads the environment body in math mode.
