latex2e: Math formulas

 
 16 Math formulas
 ****************
 
 There are three environments that put LaTeX in math mode:
 
 'math'
      For formulas that appear right in the text.
 'displaymath'
      For formulas that appear on their own line.
 'equation'
      The same as the displaymath environment except that it adds an
      equation number in the right margin.
 
    The 'math' environment can be used in both paragraph and LR mode, but
 the 'displaymath' and 'equation' environments can be used only in
 paragraph mode.  The 'math' and 'displaymath' environments are used so
 often that they have the following short forms:
 
      \(...\)   instead of   \begin{math}...\end{math}
      \[...\]   instead of   \begin{displaymath}...\end{displaymath}
 
    In fact, the 'math' environment is so common that it has an even
 shorter form:
 
      $ ... $   instead of   \(...\)
 
    The '\boldmath' command changes math letters and symbols to be in a
 bold font.  It is used _outside_ of math mode.  Conversely, the
 '\unboldmath' command changes math glyphs to be in a normal font; it too
 is used _outside_ of math mode.
 
    The '\displaystyle' declaration forces the size and style of the
 formula to be that of 'displaymath', e.g., with limits above and below
 summations.  For example:
 
      $\displaystyle \sum_{n=0}^\infty x_n $
