June SAT Math II Thread

<p>@jackfrost: I got 60 also
it might have been .27. I just remember getting 0.32 for something but it was probably for a different problem</p>

<p>but it is gave a domain that was 0<x<90 and the only times that it equals 1 in the first quadrant is at 90 so it does not fall in the domain. It was undefined.</p>

<p>It also got 60
then 30 for n^k
and undefined =)</p>

<p>it said that ln(sinx) = 0. that would mean sinx = 1</p>

<p>@midwest: its not undefined, the answer was in radians! I was confused about the 0<x<90 thing during the test too so I omitted the question. I only realized that after someone on this thread explained :(</p>

<p>SUCH A JOKE OF A TEST. finished with 20 minutes to spare! i only skipped one. 800 here we come!</p>

<p>^Does coming on here and bragging about how well you did make you feel good about yourself? I bet it does. I would also bet that you don’t have any friends to brag to, that’s why you come on here. I can’t tell if you’re joking or not, though.</p>

<p>Anyway, I’m really confident that the #50 was I and III. I spent a good chunk of time on that, and made sure of the answer. It’s just one of those things you have to think about for a little while to get. It asked for which of the following COULD be true, not which of the following are always true, fyi.</p>

<p>@bookworm2049 cool beans. you are an awesome person and the sun shines out of your a$shole. congratulations on winning life.</p>

<p>haha uhh I really hope you’re ■■■■■■■■…</p>

<p>^■■■^</p>

<hr>

<p>I wonder what a ■■■■■’s life is like…o wait…they don’t have one</p>

<p>@born2dance the answer was 123, I cant remember the question though. I’m pretty sure it involved like “the products of 3 numbers equals something”</p>

<p>Can the curve for an 800 possible be 42?</p>

<p>^Someone earlier said 4 or 5 wrong is 800, but that seems kinda harsh. 42 would be nice :)</p>

<p>the actual question was
sina 2x> sin x
cos x> cos 2x
tan x> sin x</p>

<p>I is false. 2 and 3 are true.
and im not ■■■■■■■■ lol</p>

<p>@jrp you are right i think the restriction was in radian 0<x<pi/2 but i still think it was undefined because the problem said the ln(sinx)=0 so that means that sinx had to be 1. one was not in the domain, therefor it was undefined</p>

<p>^how was it not in the domain?</p>

<p>For those interested, these are the curves for four of the college board released tests in their books:</p>

<p>42-50: 800
41-790
40-780
39-770
37-38: 760
36-750</p>

<p>43-50: 800
42-790
41-780
40-770
39-760
38-750</p>

<p>43-50: 800
42-790
71-780
40-770
39-760
38-750</p>

<p>44-50: 800
43-790
72-780
41-770
40-760
39-750</p>

<p>The high for an 800 is 44, while the low is 42.</p>

<p>^That makes sense. Why the hell would you have to type in ln(90) as ln(pi/2)…there’s a reason why calculators have a degree and radian mode. Can i get some mathematical reasoning as to why you guys say it’s not undefined, instead of just “the answer was in radians!”. I’m sorry to be blunt, but again:</p>

<p>ln(sin(x)) = 0</p>

<p>means that sin(x) = 1</p>

<p>The only way sin(x) = 1 is if x is 90 in DEGREE mode and pi/2 in RADIAN mode. Since 90 isn’t in the domain of the function, then the function can’t be 0. The solution is undefined.</p>

<p>^^You are correct. It was undefined. I even used my Ti-89 with a domain restriction 0<x<90 to make sure.</p>
