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} \tag{#}...\ end{equation) (Note: no space between the '\' and the 'begin' or 'end). Enter the number desired within the \tag{} field.
For example, this equation: \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}
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.
