<p>^I wholeheartedly agree…If i can remember any, I will bring them up.
But after reviewing this whole thread, I know i have 6 skipped and 2 confirmed wrong. This puts me at 42 raw score…would this put me at 780 or 790, and if so, is it worth canceling?</p>
<p>I plan to major in aerospace engineering at MIT…so 800 is basically required…:(</p>
<p>^agreed! the perfectionist within me won’t be satisfied unless i get 800 :(</p>
<p>I remember one that asked something like which quadrant these 2 lines intersected… it was like f(x)=cx+3 g(x)=dx+1 or other way around and 0<c<d…</p>
<p>and another one that had something to do with the Stem Plot, which was really easy…</p>
<p>and one about quadratic regression? I forgot the specifics…</p>
<p>that’s it.</p>
<p>OK I’ll update the list…</p>
<ul>
<li>f(4.7), where f(x-1) if x is greater than 1 and f(x) if x is equal to or greater than 0 and less than one → answer: 0.7</li>
<li><p>intersection between ellipse and y=x → answer: (3.12, 3.12)</p></li>
<li><p>given the diagonal of a small cube (1.414) find the volume of the large cube made of 27 of the small cubes → answer: around 27</p></li>
<li><p>function f times function g produces how many zeros → answer: 6</p></li>
<li><p>birds on the island → answer: 6000</p></li>
<li><p>4, 5, 8, 8, 12, and an unknown integer → answer: integer is 11</p></li>
<li><p>rate of taxi (or telephone; it differed from test to test according to some) → answer: $1.25 + $0.75(x) where (x) is the smallest integer greater than or equal to x</p></li>
<li><p>r = cos(theta) → answer: (0.5, pi/3)</p></li>
<li><p>surface area of the cylinder → answer: 6(pi)(r)^2</p></li>
<li><p>number of triangles formed → answer: none</p></li>
<li><p>(x^-2m)(x^m) → answer: 1/(x^m)</p></li>
<li><p>arrangement of 8 cars with two in set positions → answer: 6!
-which y is not a function of x → E, or the one that did not pass the horizontal line test</p></li>
<li><p>standard deviation of the student’s score when compared to the rest of the class → answer: A (no one has posted a number)</p></li>
<li><p>x^2 +4 = 8 logic problem → answer: number 2 only (choice B)
-1.5x increase per year in population → answer: 338 (choice A)
-function was something like 3sin(2x+1) - 1 → -4<=f(x)<=2</p></li>
<li><p>f(x)=cx+3 g(x)=dx+1 → answer = quadrant 1, i graphed it</p></li>
<li><p>stem plot answer → 56 (according to some sources, i don’t remember what i put)
-terminal side → cscx < 0 ; secx > 0</p></li>
</ul>
<p>hahaha ah the perils of ivy hopefuls…</p>
<p>so i should probably cancel, eh? I’ll take it in october then, as I am taking the real SAT this June…three months of summer prep (not really) should be overkill</p>
<p>The two lines intersected in the first quad. The stem plot one was like 50something i believe…and the quad regression one was 22.4 i think.</p>
<p>Anyone remember the one asking when a fraction would be negative (or maybe it was positive)?..</p>
<p>@theexyw - for the stem plot one, I got 56 as the median and for the f(x) and g(x) and their intersection, I put that they intersect in the first quad. Is that what you got?</p>
<p>meepster check the list ^</p>
<p>r = cos(theta) → answer: (0.5, pi/3) can someone explain how you got that?</p>
<p>looks like a lot of ivy hopefuls are canceling and retaking in june 
including me</p>
<p>@hopefully, it is polar. it is written in the format (r, theta). so if theta is pi/3 or 60 degrees, cos60 is 1/2 or .5, which is r.</p>
<p>I might still have a shot at an 800, but i’m cutting in close. What’s the harm in keeping a 780-790 and retaking it in october?</p>
<p>polar form coordinates = (r, theta)
so .5=r, pi/3=theta
cos(pi/3)=.5
.5=.5</p>
<p>pretty sure thats how you do it</p>
<p>I think MIT has been quoted as saying there is literally no difference between a 750 and an 800 to them. While I’m sure there is some difference, it’s really minute and is not worth the retake.</p>
<p>@hopefully: Plug in the coordinates. It’s just a relationship. When you plug pi/3 into cos(theta), you get 1/2. So that’s the coordinate point.</p>
<p>@infamous thats false</p>
<p>The equation r=cos(theta) was given. Ill make theta=y for simplification. </p>
<p>(r,y)
(.5,pi/3)
X=.5(cos(pi/3))
X=.5(.5) which is NOT the x coordinate for pi/3. </p>
<p>With pi/4 u get the rightx coordinate. </p>
<p>Ur finding polar coordinates but to check it u make sure the x coordinate equals the rcos(y)</p>
<p>lol it’s been 12 hours and the same people keep coming back to this thread.
we have to cancel by wednesday right?</p>
<p>I don’t think there is any significant harm on your application, but i feel like getting a 790 then retaking for an 800 will look snobby to admissions counselors. If I were you and I know that I can get an 800, i would just cancel and retake.</p>
<p>YoungDerivative, you have a fundamental misunderstanding of polar coordinates. Go ahead and graph r = cos(theta), go to the table set, select ASK for independent, go to the table, and type in pi/3. You will get 1/2 for r. Unfortunately, you’ve confused yourself with the formulas for converting between rectangular and polar coordinates. You’re also getting hung up on the unit circle (thinking the graph is the unit circle, not its own distinct graph).</p>
<p>so is a 42 on this test (given what you guys think about difficulty) a 780? if its 790 or above, im not canceling…sounds crazy but i want perfect or near perfect (within 10 scaled points)</p>
<p>Wait can anyone confirm if it was x=rcos(theta) or r=cos(theta)</p>
<p>it was r=cos(theta) ^^</p>
<p>YESS thank you.</p>
<p>tigerman, a 42 can be a 780 or a 790. I’m not sure which is more likely. It really depends on the curve.</p>
