How would I go about adding a subscript to a symbol I'm defining from an equation. For example I have an equation
E_m = \alpha_m x + y
How can I then do something like \emph \alpha\textsubscript{m}
The above gives me errors and I can't figure out how to correct this.
$\alpha_m$--\emphusually sets its argument in italic, and that's the usual math style. – barbara beeton May 2 '12 at 15:45\(E_{m}=\alpha_{m}x+y\): TeX will take care of the details of math mode. – egreg May 2 '12 at 15:45$E_{m} = \alpha_{m} x + y$will give you italics, and$E_m = \alpha_{\mathrm{m}} x + y$will give you a roman subscript. – Peter Grill May 2 '12 at 16:44
