Trig and Stats in QR

Hi guys,
In studying for my DAT, I'm concerned about the amount of questions that come from Trig, as being in a math class has been so long ago for me. Things like trig identities have always tripped me up, and I wasn't sure if the section relied upon data analysis or a mixture of general math.

Does anyone remember the depth of stats and trig that's usually covered in the section? I'm not sure of how one could be asked to calculate things beyond standard deviation, permutations and combinations.

Thanks!

I had like 3 on my exam, none were very in depth

For trig know the basic angles (0° 30° 45° 60° 90° 180°) and their equivalent in radians ( in terms of π). Know sine cosine and tangent of these angles and also know the basic trig identities.

But remember some versions of the DAT have zero trig..but you can't take any chances..it's just the nature of the DAT!

Hope this helps!

I had a question asking which one of the following is not a trig identity.
It was basic though as long as you know your basic trig rules/identities, you should be fine.
I had ~3 trig questions both times I took the exam.
I personally think I could place a few questions under statistics. They can all be solved with 0 stat knowledge though, however, the more you know, the quicker you can solve the problem

I took it yesterday and had two trig questions, both much less in depth that I was expecting. One was finding the equivalent angle expressed in radians in a different quadrant, and the other was something like finding the length of a side of a triangle using arctan or something. Nothing with complex identity manipulations and rearrangements. I did the 32 trig quiz problems on coursesaver's chads vids the day before because I thought my trig was a little weak and I think it was a good representation of the level of difficulty of trig you'll see on the test.

Khan Academy videos / youtube tutorials can teach you everything you need to know. 80% of the DAT trig is fairly straightforward
