October 2009 SAT II - Math Level 2

<p>@bacdgk
I just got minor arc lenght of 0.928 for that one. I can’t believe I missed this one. ****.</p>

<p>I got -sin x and abs(sin x), and 29.69.</p>

<p>also want was the answer to sin(theta) = .960 and tan(theta) = -2.14…find cos(theta)? anyone know?</p>

<p>for the sequence question i got U1 as 5 as well</p>

<p>easy, tan x= sin x/ cos x, so answer = .960/-2.14</p>

<p>hey was one of the answers choices for the cube and triangle perimeter 3 on the square root of 2? because i think i read it as the sides were 1, not 7. so i may have just put 3 on the square root of 7?</p>

<p>Twaan, it was a negative 42 something if I recall. Either way, you take sin-1 of 0.960, take the angle and find what costheta is. Then, the sign is negative because tan is negative.</p>

<p>i got -0.44859 if ur values are right for the question</p>

<p>so for the one where it was like a line has the points (something, something) and (something, y). and it asked for the value of y if the line is perpendicular or something?</p>

<p>the answer is 4.8 to the cone question.</p>

<p>i hope there’s a big curve otherwise im gonna take it again…</p>

<p>What did everyone get for number 50? I got 3.77… nvm I multiplied by the wrong number…</p>

<p>Perpendicular thing I got -1. I remember messing up finding the slope, I may have messed up on my second try lol</p>

<p>Considering the difficulty of the test what do you think will the curve be? Has the test ever been THIS HARD?</p>

<p>oh yea perpendicular question… anyone remember the answer?</p>

<p>The one with the arc from A to B was .938, because it was a unit circle so you can take sin(.08), find the degrees, and then do a ratio with the circumference. For the one with P=(-2,-3), i got -2/root 13…because sin is -2(opposite) over hypotenuse…did i screw that up?</p>

<p>i also got 7.7 % increase and 0.99 something for the alarm. i got 30% for the jeans. </p>

<p>…i read sinx and abs sinx instead of NEGATIVE sinx. dammit.</p>

<p>I thought it was monstrously easy…</p>

<p>There shouldn’t be a good curve.</p>

<p>i just thought this test had too many hard function questions. I would have aced a test with more of trig, complex numbers, conic sections and logs… but this didnt have much of it</p>

<p>Was .938 for the arc choice E, or at least the biggest number there?</p>

<p>im w/red, althougth im kind of scared because i always do bad when i think i did good and vice versa</p>

<p><em>crosses fingers for 800</em></p>

<p>I thought this test was pretty easy, but I already missed 2 and skipped 1…</p>
