June 2010: Math II

<p>For the laser question, I believe the work I did was 225 * 5280 * tan(.05) - 50, which came out to 986.7. I can’t remember if that was answer D.</p>

<p>d was 1037 or something</p>

<p>What do you think the curve will be? Hoping for a 43 because i skipped 5 and guessed on two.</p>

<p>I did arctan(50/(225*5280)) to get the actual angle. Then I added .05 degrees to this angle to get the error-shift. I’ll call the new angle “a”</p>

<p>Then I believe I set tan(a) equal to x/(225*5280), x being the “new” radius. Then subtracted 50. Got 1037, D.</p>

<p>were the last five from 46 aaced</p>

<p>Last one I just drew a new right angled triangle and used sine rule…</p>

<p>I could have sworn the laser problem said that the disk was DIRECTLY above the Earth’s surface, implying that the initial angle was zero from the normal of the Earth’s surface.</p>

<p>I left 12 blank and assuming I go at most 3 wrong is it possible to score a 700 or above. The sparknotes math 2 tests were nothing compared to this test >:o</p>

<p>i forget what question it was, but did anyone get that only III was true?</p>

<p>I agree with Keasbey Nights…I drew my angle from the normal and so ended up with 987 (I believe it was 987…I know for sure that I didn’t get anything above 1000)</p>

<p>Yeah, the answer I got rounded to 987. The distance from the center of the disk to the point of error was 1037, but the problem asked you to measure it from the edge of the disk.</p>

<p>idk i think its 1037 im pretty sure. wat was the value of f(x) when g(x)=0</p>

<p>@@SamWhich</p>

<p>yeah, the rounding was kind of off. i mean if the test is checked over so many times, how did that happen? @_@</p>

<p>i took it today, it wasnt that bad butt i used princeton review & there were like 6 questions that princeton review did not cover at all. & the matrix review in princeton review is ridiculous. you dont have to do the det by hand. they should have shown you how to do it with your calc. it takes 5 secs. good thing i already knew how to do it…but the test didnt had matrixes so haha</p>

<p>6 questions may seem insignificant, but i think it probably adds like 30 point. ughh, like the one with the 2/5 and 3/5…huh??? and the questions involving slopes with trig functions was confusing. …& then there was the judge one. what??? i basically just guessed.</p>

<p>im just hoping for a 620 …and on another note, the princeton review for biology is okay. its clear and quick so thats good. you shouldnt use it alone though. find that out after i took it >.> …probably got like below a 600 on that one. ahhhhhh, my fault for not preparing.</p>

<p>The distance that I calculated from the center to the point of error was 1087.</p>

<p>I can’t remember the darn wording on the problem… but I know something in it made me want to use arctan(50/(225*5280)) as the base angle.</p>

<p>Yeah the (x^2)^3 question was complete bs even though I got it right. None of the answers came out to be exactly what they should have been.</p>

<p>oo man i totally thought the volume/x axis was a cone.</p>

<p>this burnns</p>

<p>sooo much easier than i was expecting! 800, finger’s crossed</p>

<p>I’m pretty sure it is a cone? A rotation will create a circular base as far as I’m aware…</p>

<p>So what could 12 blank and 3 wrong get me a 700 or higher?</p>

<p>How are you guys getting 1037 on the satellite question?
I got 1037 as the base without subtracting the 50 (radius of disk) from it and then realized it said edge, so I subtracted and got 987 as the answer.
I’m pretty sure everyone had the same triangle…</p>
