What are some basic trig properties you should know for the QR?

I am trying to memorize all of them. I took calculus 1 and 2, so I know most of them already. I just need to brush up on a few and work on my speed. I tend to go into a stupor after a few hours of studying and then taking practice exams, so my brain just dies towards the end of these 4 hour practice exams. Nonetheless, I find QR very doable in the practice exams. I just hope the real DAT is the same, if not easier. The calculations in topscore totally takes most of my time imho.

I think all u gotta know is sin,cos,tan...stuffs

maybe 30-60-90 , 45-45-90 triangles with its opposite side length ratios.

and then sin graph, cos graph stuffs...


I think that's all...what else r there? i can't think of it now.
