How much trig has been on the QR part for people who have recently taken the DAT? I am really good in algebra and I am fine with Soh- cah- toa and the unite circle but I never get trig identities right. Were there a lot of those questions on the QR part?

a LOT of trig.. do NOT underestimate your trig. review your identities (double angle, etc.), obviously know your unit circle/sohcahtoa, but also know how to apply them in a word problem (especially the whole building that's x feet tall with y feet shadow etc.)

Okay thanks I am going to review them these next two days. I am good at those shadow problems my biggest weakness is the problems like (sin(x)+cos(x))^2= ... The answers seem simple when I review them but I just can't seem to remember all of the identities under a time crunch.
