EquationRef
The pair of templates {{EquationRef}} and {{EquationNote}} is used for labeling equations in text. The following equation:
- Predefinição:EquationRef [math]x^2+x+1=0[/math]
Is typeset by :{{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 the following call to {{EquationNote}}: {{EquationNote|Eq. 1}}. This produces a link Predefinição:EquationNote to equation Eq. 1.
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|2}}}} gives
{{#if::|Erro de script: Nenhum módulo desse tipo "String".|}}

which may then be referred to by {{EquationNote|2}}.
