টেমপ্লেট:সমীকরণ সূত্র
(টেমপ্লেট:EquationRef থেকে পুনর্নির্দেশিত)
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}}}}
(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}}}}
(Eq. 4)
- which may be referred to by {{EquationNote|4|||||||||}} (i.e., 4).
{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|Eq.5}}}}
(Eq. 5)
- which may be referred to by {{EquationNote|Eq. 5|||||||||}} (i.e., Eq. 5).
