Hi Bill,

If you want to use a package that is not internally supported by LyX, 
you have to add it manually in the preamble and put the desired command 
into a TeX Code inset (aka ERT).

Add the package to the preamble:
1. Select "Settings" in the "Document" menu which opens the "Document 
Settings" dialog.
2. In the dialog, select "LaTeX Preamble" on the left side and put

\usepackage{actuarialsymbols}
\usepackage{actuarialangle}

3. Press "OK" in the dialog.

Put the command into a TeX Code inset:
1. Put the cursor where you want to add the command in your document.
2. Insert "TeX Code" from the "Insert" menu (there is also a shortcut 
indicated next to the menu which allows you to do this quicker).
3. In TeX Code inset (red box) add your command, e.g. \actsymbol{A}{x}.
