{{EqRef}}

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>
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>
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}}}}

$x^{2}+x+1=0$

(3)

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}}}}

$x^{2}+x+1=0$

(Eq. 4)

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

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

$x^{2}+x+1=0$

(Eq. 5)

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