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.

AutoNumbered Equation

To produce a numbered equation in a wiki document, simply surround the LaTeX for the equations by the following: \ begin{equation} \label{}...\ end{equation) (Note: no space between the '\' and the 'begin' or 'end). The equation number will be automatically incremented, but will not be shown unless desired.

For example, this equation: \begin{equation} \label{} \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} \label{}
   \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 \label{}. Be aware that the numbering for this equation is still incremented, just the number is not displayed.

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}
