Template:DisplayEquation

The template takes three named parameters, width, eqn and no, being the equation width (default 610 pixels), LaTeX expression and the equation number respectively. All parameters are optional, but only two combinations of eqn and no are useful:

{{DisplayEquation|eqn=a^2+b^2=c^2}}

$\displaystyle {a^{2}+b^{2}=c^{2}}$

{{DisplayEquation|no=28|eqn=\frac{\partial\rho Y_k}{\partial t}
+\frac{\partial\rho u_iY_k}{\partial x_i}=
\frac{\partial}{\partial x_i}\left(\rho D_k\frac{\partial Y_k}{\partial x_i}\right)
+\dot{\omega}_k\qquad \text{for } k=1,2,\dots,N}}

$\displaystyle {{\frac {\partial \rho Y_{k}}{\partial t}}+{\frac {\partial \rho u_{i}Y_{k}}{\partial x_{i}}}={\frac {\partial }{\partial x_{i}}}\left(\rho D_{k}{\frac {\partial Y_{k}}{\partial x_{i}}}\right)+{\dot {\omega }}_{k}\qquad {\text{for }}k=1,2,\dots ,N}$

$\left(28\right)$

Note that equation labelling is not restricted to numbers:

{{DisplayEquation|no=\text{axiom }M3|width=300|eqn=\rho(a,c)\le\rho(a,b)+\rho(b,c)}}

$\displaystyle {\rho (a,c)\leq \rho (a,b)+\rho (b,c)}$

$\left({\text{axiom }}M3\right)$

Bugs

• Do not break an equation line at an equals sign. Break it somewhere else or use the equals sign template.
• It may be necessary to separate off the closing double right braces of the template by a space from preceding right braces in the LaTeX source.
• Subscripts of more than one character (enclosed in curly brackets) may cause problems.
