**SAT 2 Math II Discussion Thread Nov 2015**

did you guys get sec(x) for one of your answers the one asking sin(2x), and to get it symplified to 2sin(x)

I prepped with Barrons but i dont think the actual test was what Barron’s taught me. I had heard that Barrons overpreps you but I didnt feel like that during the test. Just my opinion.

Hey guys, what was the matrix question even asking? Also for the question where it was like f(x)=abs(f(x)) is it x^2?

I got x^2 for the second question and no idea for matrix lol… D:

Also, for the sin2x question and the secx question, what was the original question asking?

@basedchem I don’t remember exactly but I remember brute forcing it and getting sec(x), I’m 99% sure that’s the answer

did u guys get something like sin (or could be cos cant remember) (pi/2 - theta) for one question?

thought it was pi - theta

Yea people talked about it earlier it was pi - theta

guys what do you think 40/50 will be? Possibly a 780 still?

btw guys we had the exact same test as May 2013 http://talk.collegeconfidential.com/sat-subject-tests-preparation/1501025-may-2013-mathematics-level-2-p3.html

That’s useful thanks for posting

wait that’s so cool! thanks :smiley:

So for the next test are they going to reuse the June 2013 test? :smiley: goes and memorizes every answer from June 2013 thread

@jaimk123 You get -2x = x^2 by plugging 0 into y. You can’t divide by x because x could be 0 (and in this case, it actually is). Add 2x to both sides to get x^2 + 2x + 0 = 0. (x+2)(x-0) = 0. Thus, two solutions.

(i got this one wrong, but now understand it) :frowning:

@Collegewhat I actually just checked March 2013 math 2 test thread and the october 2015 math 2 test thread and they are unfortunately not the same haha…

Does anybody know what the second to last question was?

@collegeguy123456 I got “A”. Anyone else got the same?

I think i omitted it, but what was the question asking?

I don’t remember the question… is this for core?
