Usage
The template takes two named parameters, eqn and no, being the LaTeX expression and the equation number respectively. Both parameters are optional, but only two combinations are useful:
{{DisplayEquation|eqn=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}}
Note that equation labelling is not restricted to numbers:
{{DisplayEquation|no=\text{axiom }M3|eqn=\rho(a,c)\le\rho(a,b)+\rho(b,c)}}
