EquationRef
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> results in:
- Predefinição:EquationRef [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 Predefinição:EquationNote to this equation.
Similarly, :{{EquationRef|2|Eq. 2:}} <math>x^2-2x+1=0</math> results in
- Predefinição:EquationRef [math]x^2-2x+1=0[/math]
which can be referred to by {{EquationNote|2}} (i.e., Predefinição:EquationNote) or even {{EquationNote|2|Equation 2}} (i.e., Predefinição:EquationNote).
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}}}} gives
{{#if:::|Erro de script: Nenhum módulo desse tipo "String".|}}
thin solid|none}}; padding:0.08em;" class="nowrap"| [math]x^2+x+1=0[/math]
|
thin solid|none}}; padding:0.08em;"|
|
thin solid|none}}; padding:0.08em;" class="nowrap"| {{#if:|Predefinição:EquationRef|({{ safesubst:#if:1|Predefinição:EquationRef}})}} |
{{#if:::|Erro de script: Nenhum módulo desse tipo "String".|}}
- which may then be referred to by {{EquationNote|3}} (i.e., Predefinição:EquationNote) or even {{EquationNote|3|Eq. 3}} (i.e., Predefinição:EquationNote).
- {{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|4|Eq.4}}}} gives
{{#if:::|Erro de script: Nenhum módulo desse tipo "String".|}}
thin solid|none}}; padding:0.08em;" class="nowrap"| [math]x^2+x+1=0[/math]

{{#if:::|Erro de script: Nenhum módulo desse tipo "String".|}}
- which may be referred to by {{EquationNote|4}} (i.e., Predefinição:EquationNote).
- {{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|Eq.5}}}} gives

- which may be referred to by {{EquationNote|Eq.5}} (i.e., Predefinição:EquationNote).
