*OFFICIAL* January 28, 2006 SAT Thread

<p>I don't know. I put that it challenges recent scientific research, but other posters seem to think it's an alternative viewpoint. I guess we'll have to wait and see.</p>

<p>Um....I got 7 for the box perimeter. The sides were 0.5 because they create an area of 0.25. why is that wrong. How can sides of 0.25 equal to an area of 0.25??</p>

<p>It's 2+1+1+1+1+1/4+1/4=6.5</p>

<p>Does anyone have the curves for all of the sections in the 700 ranges??</p>

<p>Please post it :)</p>

<p>Why is it 0.25 for the sides...explain!!!</p>

<p>The perimeter question, are we even talking about the same one? The one where they gave you the area?</p>

<p>For one of the multiple choice questions, something about 4 units from the origin.</p>

<p>Did you guys get 4 or more than 4? (D or E?)</p>

<p>I think I put D) 4.</p>

<p>its more than 4
because there are an infinite number of points with a distance of 4 from the origin (think of a circle)</p>

<p>I put E) more than 4. The point doesn't necessarily have to be on the X or Y axis. Did it say it had to be on an axis? Oh, man, now I'm getting post-SAT anxiety.</p>

<p>Yeah but it said 4 UNITS.</p>

<p>Okay, (4,0), (0,4), (-4,0), (0,-4) are 4 UNITS away, but take (2,2)...the distance is 2.82 (units?) away</p>

<p>units is just the word used in place of a unit (like inch, cm, etc)
do you understand what i mean by the circle thing?</p>

<p>No, but do the distance formula:</p>

<p>(0,0) and (4,0) = 4
(0,0) and (-4,0) = 4
(0,0) and (0,4) = 4
(0,0) and (0,-4) = 4</p>

<p>but..</p>

<p>(0,0) and (2,2) = 2.82
(0,0) and (3,1) = 3.16</p>

<p>i know you can have the points:
(cosX, sinX) that form a circle with radius 4 around the origin</p>

<p>Try it:
(cos45, sin45) SHOULD equal (as you say) 4..</p>

<p>(0,0) and (.707, .707) = 1</p>

<p>There are an infinite possibilities that give 4 units as the distance. I pictured a line that was 4 units long from (0,0) to (0,4) and it rotating around in a 360 degree angle.</p>

<p>Just rotating a uniform distance cannot change its unit of measurement, so there are infinite amount of possiblities because the line can be rotated to any position.</p>

<p>sorry i meant 4cosX, 4sinX becuase the radius is 4 and not 1
try it.</p>

<p>exactly, sourapplezz, its like using a compass and drawing a circle that passes through the points (0,4) (4,0) (-4,0) (0,-4)
and notice: every single point on the circle is 4 units away from the origin.</p>

<p>Awww you're right haha.
I thought it was more than 4...but I thought it was a trick or something.
Ahhhhh whatever.</p>

<p>I think "units" threw me off...or I was thinking of integers...or being plain stupid.</p>

<p>yeah i think they put that in there to throw ppl off. the parametric equation (giving the circle) is used a lot in trig anyway.</p>

<p>I even drew the stupid circle on my graph.
I feel so dumb. AH WHATEVER!</p>

<p>I already know I bombed this SAT.</p>
