<p>ahh sorry wrong question yea its I only</p>
<p>lhDCpage06: was that problem toward the very end of the test? Like >40</p>
<p>I posted a response above about the inverse and how it is not a reflection over the origin.</p>
<p>OMG UR RIGHT IT IS y=x OMG im soooo stupid ARRRGH stupid mistakes :@</p>
<p>crap, 3 wrong.</p>
<p>If anyone wants to try and estimate the curve, use the results from the June 06 test (same tests)</p>
<p>yes! it is y=x. :)</p>
<p>Omitted four, around six wrong already... eeegh.</p>
<p>anyone remember seeing a l'hopital's? 5?</p>
<p>For the limit question, I just factored out the top term, and canceled a term out, and plugged in the limit.</p>
<p>Would that be a correct method? I don't remember the answer, and I didn't graph or anything, except simplify so that I could plug in the limit value.</p>
<p>the limit problem? it was really basic; you could have solved via factoring.</p>
<p>oh I didn't even think about cancelling >_></p>
<p>The limit was 5 i think</p>
<p>I got pi/2 for the period of tangent (was this right?)</p>
<p>and then I got I and III for checking the functions</p>
<p>how is it over y=x?
if it is y = x then it could also equal y = -x</p>
<p>for example y = x
inverse is still y = x</p>
<p>and y = -x
x = -y
so y = -x</p>
<p>Yeah, thats what I did! I facotred the term and then cancelled out the denominator. Hope that is correct. I was going to graph it, but it was way simpler the other way.</p>
<p>Classof08, can you explain your reasoning?</p>
<p>For the limit, l'Hospital's could have been used, but factoring would work just as well.</p>
<p>So still no settlement about the reflection thingy?</p>
<p>What was the exact question again?</p>
<p>In any case, you guys might like to know we've passed the Biology thread in number of posts.</p>
<p>Im just saying, for example y = x
then the inverse is also y = x right?</p>
<p>but y = -x the inverse is also y = -x</p>
<p>so why would the answer be reflection over y = x instead of y = -x?</p>
<p>yes it is reflection y=x, becuase your example y=-x is symmetrical about the line y=x</p>
<p>yeah but isnt the line y = x symmetrical about the lin y = -x?</p>
