Just want to do a quick survey. Has anyone actually gotten any questions their QR portion that requires the use of either the double angle formula and half angle formula?

Thanks.

I hope not! Those are rather specific type questions for the scope of the DAT. I'd imagine it's too low yield to worry about.

I wouldn't bother. Know the trig identities and the unit circle. If you ever encounter a problem where you need to use either formula, I would advise marking the question and moving on.
