Template:EquationRef/doc

The pair of templates {{tl|EquationRef}} and {{tl|EquationNote}} is used for labeling equations in text.

For example,

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

(Eq. 1) $x^2+x+1=0$

Here, the identifier "Eq. 1" is a label which can be later referred to with a call to {{tl|EquationNote}}. That is, {{tlb|EquationNote|Eq. 1}} produces a link {{EquationNote|Eq. 1}} to this equation.

Similarly,

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

(Eq. 2:) $x^2-2x+1=0$

which can be referred to by {{tlb|EquationNote|2}} or even {{tlb|EquationNote|2|Equation 2}} (i.e., (Equation 2)).

This template can be used together with {{tl|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 {{tlb|EquationNote|3}} or even {{tlb|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 {{tlb|EquationNote|4}} (i.e., (Eq. 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 {{tlb|EquationNote|Eq. 5}} (i.e., (Eq. 5)).

The common shorthand (#) can be written using {{template|EqNote}}, e.g. Template:Tlb gives ((5))
