<p>Still drawing a blank. Now I am seriously thinking I missed it intentionally, but forgot to get back to it. I usually skip wordy problems to keep a constant pace; I have never messed up the answer sheet: I mutter 21A, 22B, 24E, etc… when I bubble in. I also write a LARGE letter of my answer right next to the question number in the booklet. To save time I also bubble in two open pages at a time - except in the last ten minutes.
Gotta be more vigilant about skipped questions now. >.<</p>
<p>The one where they asked you the ctr of I think it was a circle, does anyone remember the equation? The answer was (3, -2)? All you have to do is divide the coefficient of the x and y by two and then negate it right?</p>
<p>i can’t remember how that equation looked like, but if it was (x-3)^2(y+2)^2=bla, then yes</p>
<p>what was the question about linearizing data? and what was the answer too? anybody remember?</p>
<p>? I don’t remember anything about linearization…</p>
<p>“conic (circle) (2,3)”</p>
<p>pretty sure there was a negative in there…</p>
<p>I’m pretty sure it was (3,-2)</p>
<p>lolilaughed is right</p>
<p>What was the curve for last month’s test? What is the minimum raw for 790 and 800 (approximately)?</p>
<p>Did you guys think this was harder or easier than last month’s (better or worse curve)?</p>
<p>anyone remember what the equation for the period question was. they asked the period of some trig funtion. when i graphed i distinctly remember seeing the graph take 8 periods to complete its cycle. each period (on the x-axis) corresponded to pi/2 so that would be 4pi but ppl say it was 2pi so how is that, anyone knows what the equation was, it doesnt have to be exactl it might help me remember</p>
<p>It was 4pi.</p>
<p>i can’t remember but maybe you made a stupid mistake in typing in your calculator… I did it on calculator too and it was 2pi.</p>
<p>I just did the simple period = (2pi)/B
I think I got 4pi or something.
I just remember it was a very long and curvy graph…it had a big period.</p>
<p>wait nevermind i don’t know what i am talking about lol
confused</p>
<p>is this the same problem where y= abs(cos(x/2))+3</p>
<p>i dont think you need to do (2pi/B), once u look at the graph that equation is unnecessary but now that there is less ppl saying 2pi and since i double checked my answer at the time, im guessing my answer is right. so far… lol :D</p>
<p>I could be wrong, cause I’m using calc in degree mode (too much time to change on my calc), and I’m always forgetting that pi=180, and cout pi=360, I was even thinking about it during the test (don’t make a mistake!), but as I see, I did… Stupid girl ;(</p>
<p>hookem, it’s about honor :P</p>
<p>I omited 4 (maybe 3, can’t remember) and know I know that at least 1 wrong. So now I have max 44.75, one more wrong will be 43,5, so it’s, let’s say, dangerous :)</p>
<p>haha I’m on the brink too. 5 omits + 1 wrong (if that other one was 5 sets, instead of 4), so I’m at a raw score of 43.75/50.</p>
<p>I really can’t recall any questions other than the 6 above that I was hazy on, so I should be ok, but let’s just hope that the curve is nice :)</p>
<p>HARDER OR EASIER THAN OTHER MATH II tests?</p>
