June 2 Math II Study Thread!!

<p>hey circular permutations are not a huge part of SAT II MATH rite?</p>

<p>Barrons is usually harder so i wouldn't worry.</p>

<p>I like how I'm not ready for this test. At all.A
And yet I'm taking it tomorrow.</p>

<p>Go me! Wowwwww.</p>

<p>You can not really "predict" your score on this test.
Here are my practice test scores from the Official SAT II Math 2 Tests.
Test 1: 770 Taken on 5/31/07
Test 2: 680 Taken on 6/1/07</p>

<p>Some of the questions of this exam can be extremely exasperating.</p>

<p>Does anyone know if there are matricies on the Math IIC?</p>

<p>Also, there is a chapter on logic in the Barron's book; are those kind of questions common on the exam?</p>

<p>Thanks in advance!</p>

<p>Is it odd if I score better on Barron's than on the CB's Math II tests?</p>

<p>Then again on CB's math II tests I made a lot of stupid errors >_></p>

<p>Go 700+ tomorrow!</p>

<p>Anyone know of any little-known formulas?</p>

<p>This is going to be the hardest test I have ever taken..I don't know anything at all..</p>

<p>lmao I did my first practice test for this like last week and after I realized how screwed I was I just said forget about it, no point in studying now.</p>

<p>i'm just looking through the book for formulas i might need at this point.</p>

<p>BTW, what the hell does it mean when they say like "arccos (.75)=41.4". How do you do arccos?</p>

<p>cmon low curve!!!
im so scared for tomorrow</p>

<p>"If n distinct planes intersect in a line and another line (L) intersects one of these planes in a single point, what is the least number of these n planes that (L) could intersect" </p>

<p>From the real practice test... Can someone explain why the answer is "n-1"</p>

<p>


</p>

<p>Arccosine is the same thing as inverse cosine. Cos^-1</p>

<p>I've been doing the practice tests in Barron and I keep getting in the low/middle 600s and in the McGraw-Hill book, I'm getting low/middle 700s. Dang, I thought I was good at math.</p>

<p>arccos is inverse cos</p>

<p>Optimus, think if you have two planes intersecting in a line... if they're perpendicular, then the line L could be parallel to one of the planes, meaning it never intersects it. You see, it says they intersect in a line, not intersect a line.</p>

<p>WOW, I'm screwed.</p>

<p>I'm almost thinking about not taking it at all (maybe taking it October or November instead) and just walking out after my first test.</p>

<p>Does anyone know if taking a Subject Test in November of your senior year is too late for Regular Decision?</p>

<p>Hmm I think I get it. I hate planes, and geometry in general. </p>

<p>Can anyone help me out with one other question:</p>

<p>"If the magnitude of vectors a and b are 5 and 12, respectively, then the magnitude of vector (b-a) could NOT be. </p>

<p>a. 5
b. 7
c. 10
d. 12
e. 17</p>

<p>Can anyone explain how to find the answer (which is 5).</p>

<p>Optimus: Consider joining the vector components as a triangle. 5 + 5 < 12 which means it can't be. The only exception would be if you have both a and b as straight lines. You would get 7, (12 up, 5 down), 17, (12 up, 5 up). The 10 and 12 are formed by having the two vectors going in different angles from each other. A triangle is one in which a + b > c for all sides. It works for 10 and 12 but not 5.</p>

<p>do we need to know matricies? thanks</p>

<p>yup .</p>

<p>Matrices*</p>

<p>And I assume so, but your calculator can help you out ;)</p>

<p>how do you convert your Barron's score to the SAT score?</p>

<p>Should we know about De Moivre's theorem?</p>
