Trig identities to know?

I was wondering what trig identities we need to know for the QR section? I have the double angle formulas down, and some other basic identities. What else do we need to know? Do we need to know all of the angle sum and difference identities?

watch chad's QR videos
also DAT destroyer QR section and/or math destroyer (i forget) contains an equation sheet with all equations you need to know for DAT QR section --> I'd learn whatever is on there

The notes that come with Chad's QR videos for the trigonometry section should include all the identities you'd need for the exam. I've got a slightly expanded version of it that I'll try to upload sometime.
