Template:EquationRef

50px Template documentation

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:

Eq. 1

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> results in

Eq. 2:

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}}}} gives

(<cite id="math_3">[[#equation_3|3]]</cite>)

which may then be referred to by {{EquationNote|3}} or even {{EquationNote|3|Eq. 3}} (i.e., Eq. 3).

• {{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|4|Eq.4}}}} gives

(<cite id="math_Eq.4">[[#equation_Eq.4|Eq.4]]</cite>)

which may be referred to by {{EquationNote|4}} (i.e., 4).

• {{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|Eq.5}}}} gives

(<cite id="math_Eq.5">[[#equation_Eq.5|Eq.5]]</cite>)

which may be referred to by {{EquationNote|Eq.5}} (i.e., Eq.5).uk:Шаблон:EquationRef
