<p>not at all, people are good at different subjects anyway and sat 2s don’t matter as much as the other things they take into account. You just need above a 700.</p>

22

<p>^ probably Caltech would have a problem with a score like 760, but I doubt anyone else would.</p>

23

<p>4 blank. blehh, was rushed at the end due to bad proctor and lack of time warnings. Rush leads to a lot of stupid mistakes and ran out of time for last 4. my guess would be 44 right 2-4 wrong 4 blank, so no 800 for me :(</p>

24

<p>and thats the university i wanted to go to : (</p>

25

<p>I only left one blank. Felt confident about the other 49. Pretty sure I got an 800.</p>

<p>I thought this exam was easier than most of the ones I’ve done.</p>

26

<p>so… we can talk about questions now???</p>

<p>do you think i still have a chance at an 800 if I skipped one and missed 4?</p>

27

<p>If you get every other question right, yeah.</p>

28

<p>only answered 44 but felt great about all of them</p>

29

<p>ok specific question:
you know the one that was like f(x)=nx… something something
and then it asked you what n could be? what did you get?</p>

30

<p>-1 or 1. it basically resolved to n^2 = 1.</p>

31

<p>an0maly, if you still remember the whole question, can you explain it to me please?</p>

32

<p>i remember i got that as an answer too</p>

33

<p>i remember this f(x)=nx</p>

<p>what can n be? it has to be one… but how can it be -1??</p>

34

<p>I remember the question, but are we allowed to discuss specific questions without repercussion?</p>

35

<p>-1 x -1 = 1</p>

36

<p>yes nardi, but how did you get to the n^2 part. thats my question…</p>

<p>also i thought the embargo was lifted? and when it’s lifted, i THINK it means we can talk about specific questions…</p>

37

<p>yeah we can. embargo lifted!</p>

<p>it was f(x)=nx
…
n^2=1
n=+ or - 1</p>

<p>does anyone know the answer to that question that was like 105 degree angle in a circle with radius of 5?
and polar coordinates? i don’t even remember those…</p>

38

<p>I got same as An0maly, the -1 or 1 for the nx question.</p>

39

<p>i believe those were 2 of the 6 i left out hahaha</p>

<p>@awkturtle - Construct an isosceles triangle, with the isosceles sides being the radii, and the base as the cord. Since base angles are equal, the base angles were 37.5. Use the law of sines from there to find the length of the sides. Alternatively, you can use the law of cosines directly.</p>
