Let's try to reference equation 1, here is the reference to equation {{mathjax}}\ref{eq:eq1}{{/mathjax}}

Let's try to reference equation 2, here is the reference to equation {{mathjax}}\ref{eq:eq2}{{/mathjax}}

Let's try to reference equation 3, here is the reference to equation {{mathjax}}\ref{eq:eq3}{{/mathjax}}
