Template:EquationRef

  The pair of templates EquationRef and EquationNote is used for labeling equations in text.

For example,  :$$ $$x^2+x+1=0$$  results in:
 * $$ $$x^2+x+1=0$$

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

Similarly,  :$$ $$x^2-2x+1=0$$  results in
 * $$ $$x^2-2x+1=0$$

which can be referred to by  $$  (i.e., $$) or even  $$  (i.e., $$).

This template can be used together with NumBlk to produce nicely formatted numbered equations. For instance:


 *   gives


 * which may then be referred to by  $$  (i.e., $$) or even  $$  (i.e., $$).


 * ''' gives


 * which may be referred to by  $$  (i.e., $$).
