<p>i remember a question that gave u an angle of 58 degrees as a given and u needed to find the length of CD…what was the answer?</p>
<p>This thread has made me pretty happy. I agree with all of the answers so far…
Omitted 4, guessed on 1. The one I guessed on was the probablility one that was like
A. 24
B. 64
C. 3,xxx
D. 7,xxx
E. 33,xxx.
I don’t remember the specific answers, (hence the x’s)
I think I put D. </p>
<p>What about the absolute value of some trig function, asking for the period. I got 2pi</p>
<p>i didn’t know what standard deviation was 
was the answer still 0.1? with the boxes/packaging one</p>
<p>If I remember correctly, the first one asked something aabout which value of x shouldn’t be in the domain…Oh forget it! I probably don’t remember it correctly. protoslg?</p>
<p>i think i got 4pi for the period</p>
<p>yeah it was 7280. for the probability one</p>
<p>and i put 4 pi on the period one? uh oh</p>
<p>The SD was 0.1. Confirmed.</p>
<p>What is the period of the cos(x/2) function??? I put (D). Is that correct?</p>
<p>7280 is correct.</p>
<p>EDIT:Everyone’s got 4pi and although I didn;'t put that, I think its correct.</p>
<p>@michael</p>
<p>i am pretty sure that 4pi is correct</p>
<p>was (D) 4pi? cause 2pi divided by 1/2</p>
<p>ohhh perfectpixie wasnt that just 1?</p>
<p>was the period one the one with the absolute value around the the trig function? i wanna say 2|cos(1/2x)| + 3 </p>
<p>if so i believe i got 2pi for that?</p>
<p>@#$@#$ you’re right. I just had a epiphany. I did it half way. fmlllll</p>
<p>2pi/(1/2) equals 4pi…</p>
<p>0.1 is the answer for the SD Q</p>
<p>but it was absolute value so theres no bottom half of the function wen you graph it… put it in your graphing calculator</p>
<p>What about the one with interval -4 to 4, how many points satisfied something (I forgot what)? </p>
<p>I put 3 (choice C I think). Is this right?</p>
<p>Pianoman-the period = 2pi/coefficient, so 2pi/(1/2) = 4 pi
but… maybe does absolute value come into play? cause then it wouldn’t go negative, and then the graph repeats itself every 2pi… :((</p>
<p>Michael, pianoman- I put D. But E is 4pi. Damn.
Was it absolute value?</p>
<p>i got 4 for the one with the interval -4 to 4</p>
<p>I think Pianoman is right, haha. Missed one now</p>
<p>im almost positive its 2pi, like michael just said^</p>
<p>and i got one for the range -4 to 4
wasnt the only possiblity (-2,-1)?</p>
