[[#math_{{{1}}}|{{{1}}}]]
The pair of templates {{EquationRef}} and {{EquationNote}} is used for labeling equations in text.
For example,
:{{EquationRef|Eq. 1}} <math>x^2+x+1=0</math>
Here, the identifier "Eq. 1" is a label which can be later referred to with a call to {{EquationNote}}. That is, {{EquationNote|Eq. 1}} produces a link Eq. 1 to this equation.
Similarly,
:{{EquationRef|2|Eq. 2:}} <math>x^2-2x+1=0</math>
which can be referred to by {{EquationNote|2}} or even {{EquationNote|2|Equation 2}} (i.e., Equation 2).
This template can be used together with {{NumBlk}} to produce nicely formatted numbered equations. For instance:
{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|3}}}}| 3 |
{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|4|Eq.4}}}}| Eq. 4 |
{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|Eq.5}}}}| Eq. 5 |
The common shorthand (#) can be written using {{EqNote}}, e.g. {{EqNote|5}} gives (5)
