Help/Simple Equations

Typically numbered equations are centered in documents. Due to the appearance of the wiki, however, all numbered equations shown on this wiki are left justified with a small indent and the equation number is right justified.

Numbered Equation

To produce a numbered equation in a wiki document, simply surround the LaTeX for the equations by the following:

{{Equation|<math> ... </math>|4}}

• Replace '...' with the LaTeX equation (without leading and ending delimiters).
• The number for the equation is the last parameter in the template. In this case the equation number is 4.

For example, this equation:

$\left({{\rho }_{s}}-\rho \right)g{\frac {\pi }{6}}{{d}^{3}}={{C}_{D}}{\frac {\pi }{8}}\rho W_{s}^{2}{{d}^{2}}$

(4)

was typed as follows:
\ begin{equation} \tag{4}
   \left( {{\rho }_{s}}-\rho \right)g\frac{\pi }{6}{{d}^{3}}={{C}_{D}}\frac{\pi }{8}\rho W_{s}^{2}{{d}^{2}}
\ end{equation}

Equation Not Numbered

If for some reason it is desired to have an equation set aside but turn off display of the equation number, just leave off the delimiter \tag{}.

For example, the above equation again: \begin{equation} \left( {{\rho }_{s}}-\rho \right)g\frac{\pi }{6}{{d}^{3}}={{C}_{D}}\frac{\pi }{8}\rho W_{s}^{2}{{d}^{2}} \end{equation}

was typed as follows:
\ begin{equation}
   \left( {{\rho }_{s}}-\rho \right)g\frac{\pi }{6}{{d}^{3}}={{C}_{D}}\frac{\pi }{8}\rho W_{s}^{2}{{d}^{2}}
\ end{equation}

Some advanced equations have multiple lines, and it may be desired for each line to be aligned at a certain character on each line. These advanced equations are described on the next page.
