Is there a way to use an equation array in lyx? I want to use : /begin{eqnarray}1+1=2\\2+2=4\\3+3=6/end{eqnarray}
I can type this in manually into lyx in latex mode, but for equations more complex than 1+1=2, I want to use lyx's math tools. When I try \begin{eqnarray} (in latex mode) then a math box equation in lyx then, in latex mode \\ another math box, then \end{eqnarray} in latex mode I get tons of errors. Any suggestions? Thanks, Ben
