Similar to an old 2011 posting here, I would like to manually tag a particular line of equation with number in Beamer. I tried using \tag{}
command but it does not work, putting in \usepackage{amsmath}
also does not help. I am working under these environments:
\documentclass{beamer}
\mode {
\usetheme{Ilmenau}
\usecolortheme{beaver}}
And here is a compilable example from my slides:
$x = r \cos \theta \tag{1}$
.
Here, ShareLatex ignores \tag{1}
but compiles the rest of the equation correctly.
Please advise and thanks for your time.
PS.: I do not have any need to reference the tagged equation later.

After a small correction of (first version of) your code:
The source of your problem seems to be inline formula, i.e. between dollar signs, not inside, say,
equation
environment.
