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.
