<p>Who took sat II math level 2 January 2011???</p>

2

<p>Just to answer the question, I did =]
Oh the message is too short…</p>

3

<p>I did. Math II and physics</p>

4

<p>I took Math II and physics. Physics stumped me. Math II was a cakewalk.</p>

5

<p>questions 1 to 25 were a joke. i mean seriously. after that, i wasnt feeling well so i didnt really do the rest… i did those questions in 30 mins.</p>

6

<p>did anyone else get ‘n’ for the average of a b c d e question</p>

7

<p>^I put ‘n’ too.</p>

8

<p>Yeah, it’s ‘n’.</p>

9

<p>this has been bothering me since i got home today, but what is
[sin^2(theta)/cos^2(theta)] +1 ?</p>

10

<p>Sec (theta) squared. It’s an identity ;)</p>

11

<p>damn. what about the one with the… points in space?
i just remember that i put “cylinder with infinite height…”</p>

12

<p>Yes, that is correct :wink: Don’t sweat it, the curve for this test is normally really lenient.</p>

13

<p>yeah so i’ve heard. the score conversion in the barrons book allows for 6 omits and still get a 800…
i’m just nervous about my stupid mistakes.</p>

14

<p>I made some really stupid mistakes too. It was my first time, and I only studied 2 days prior to the exam.</p>

<p>There’s always May :D</p>

15

<p>i bet you did really well, you nerd :P</p>

16

<p>Hey guys, do you remember the question asking for “What is the value for n” and it gives you f(x) = nx and something about f(f(x))? I put 0 and 1 only, since:</p>

<ol>
<li>For n=1, f(1) = x and f(f(x))= f(x) = x so both equal x</li>
<li>For n=0, f(0) = 0x = 0. f(f(x)) = f(0) = 0.</li>
</ol>

<p>Any number would make f(x) not equal f(f(x)). Do you guys remember the correct answer for this problem?</p>

17

<p>-1,1. ahh wth message is too short?!</p>

18

<p>Hey LovexLight, if you have time can you show me how you got -1, 1? Thanks! Also, do you remember for the question in which k=1/3, was that answer choice B or C? I remember I got 1/3, but I totally forgot what choice I marked. Thanks for your help!</p>

19

<p>well f(f(x)) = n(nx), so the only way this could equal x is if it was -1 times -1 or 1 times 1</p>

20

<p>if f(x) = 1x or -1x then f(f(x)) = 1(1x) or -1(-1x) which both equal x</p>
