That is, {{tlb|EquationNote|Eq. 1}} produces a link {{EquationNote|Eq. 1}} to this equation.<br /> <br /> Similarly, {{markup2|m=&lt;nowiki&gt;:{{EquationRef|2|Eq. 2:}} &lt;math&gt;x^2-2x+1=0&lt;/math&gt;&lt;/nowiki&gt;|r=<br /> :{{EquationRef|2|Eq. 2:}} &lt;math&gt;x^2-2x+1=0&lt;/math&gt;}}<br /> which can be referred to by {{tlb|EquationNote|2}} or even {{tlb|EquationNote|2|Equation 2}} (i.e., {{EquationNote|2|Equation 2}}).<br /> <br /> This template can be used together with {{tl|NumBlk}} to produce nicely formatted numbered equations. For instance:<br /> <br /> {{markup2|m=&lt;nowiki&gt;{{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|3}}}}&lt;/nowiki&gt;|r=<br /> {{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|3}}}}<br /> }}<br /> :which may then be referred to by {{tlb|EquationNote|3}} or even {{tlb|EquationNote|3|Eq. 3}} (i.e., {{EquationNote|3|Eq. 3}}). <br /> <br /> {{markup2|m=&lt;nowiki&gt;{{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|4|Eq.4}}}}&lt;/nowiki&gt;|r=<br /> {{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|4|Eq.4}}}}<br /> }}<br /> :which may be referred to by {{tlb|EquationNote|4}} (i.e., {{EquationNote|4}}).<br /> <br /> {{markup2|m=&lt;nowiki&gt;{{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|Eq.5}}}}&lt;/nowiki&gt;|r=<br /> {{NumBlk|::|&lt;math&gt;x^2+x+1=0&lt;/math&gt;|{{EquationRef|Eq.5}}}}<br /> }}<br /> :which may be referred to by {{tlb|EquationNote|Eq.5}} (i.e., {{EquationNote|Eq.5}}).<br /> <br /> [[Category:Mathematical formatting templates]]<br /> <br /> }}&lt;/noinclude&gt;</div>
