November 2010 MATH 2 Discussion Thread

<p>^makes sense. it’s usually 7-8 raw points off for an 800</p>

<p>Rainbow Spinkles, meet Wish On a Cupcake. Wish On a Cupcake, Rainbow Sprinkles.</p>

<p>love how this discussion is already 19 pages long lol</p>

<p>I think that they gave you 0.03 as the thickness of the paper in inches. But then they asked for its folded thickness in feet? Or something like that. Anyway, I found the thickness in inches and forgot to divide by 12.</p>

<p>

Yeah, ax^2+bx+c=x. How many real solutions are there? I put infinite…</p>

<p>ohhh thattt, no i didn’t forget to do that
thank godness! but it really wasn’t fair because i’m international, so we don’t use inches or feet. we use the metric system. however, one of my gr.8 teachers taught us that “you’ll need to memorize the imperial system! it will come into use someday!”-he was right. hahaha</p>

<p>12 inches = 1 foot horrah</p>

<p>^yes, same.</p>

<p>

</p>

<p>where a,b,c are defined constants, there are only 2 solutions; however, for the
class of functions ax^2+bx+c=x there would be infinite solutions. I forget how the question was worded.</p>

<p>I have a quick question - I took both Math I and Math II, but I didn’t register for the Math I… so I know they’re billing my house, but would I still get the scores sent back at the same date?</p>

<p>@enfield: I don’t <em>think</em> they were defined constants… I forget.
Anyone have any input?</p>

<p>^same10char</p>

<p>hmm idk i put two but i really dont remember how it was worded</p>

<p>also, what was the area of the triangle formed by the piece of a trig function… i think it was like 2sin or something? i believe i put pi/2?</p>

<p>or actually i think i put pi</p>

<p>What was the answer to the last problem, #50? The one where y^2=arctan(x) or something like that.</p>

<p>I think sec(x)+tan(x)= 1? So My answer was abs(sec(x)). What about you guys?</p>

<p>I put 2…I think the constants were defined</p>

<p>lol i left a lot of trig questions blank</p>

<p>Does anyone else love the limit questions? they are my favorite. so easy lol</p>

<p>The last trig one was abs(sec x).
For the area of the triangle, I put pi/2 i think… height was 2 and the vertices were pi/2 apart (if i remember correctly) apart. pi/2 times 2 divided by 2 = pi/2</p>

<p>for the parabola one, i put X on the other side to get ax^2 + (b-1)x + c…i put Infinite but i forgot my reasoning…</p>

<p>^yes on the pi/2</p>

<p>i dont remember which i put but if you say pi/2 thats prob what it was since thats what i first thought</p>

<p>^yeah, if i did put something for that question, then it was that</p>
