<p>i got 2 for the question with the x-intercept and 2 for the period</p>
<p>this is from a few pages back… but I confirm that sin(2x)=a, 2sin(x)= asec(x)… cause:
sin(2x)= 2sin(x)cos(x)=a
2sin(x)= a/cos(x)= asec(x)</p>
<p>lets please post a consolidated list of answers :)</p>
<p>for real ^ ^ im curious. if you for the xy^5 one or whatever all you had to do was make y 0 and solve for x cause it had to be on the x axis. i think it was 2. </p>
<p>for the period one i just put it in my graphing calculator and i didnt get 2 "/ isnt period the number that its sin of or whatever under 2pi</p>
<p>Did it say (2,3) reflected about y=-x or (3,2)…</p>
<p>If (2,3)–>(-3,-2)
If (3,2)–>(-2,-3)</p>
<p>it was (2,3) so it was (-3,-2)</p>
<p>^i dont think so, i think it was (3,2). I would actually want you to be right, since I put the wrong answer lol (-3,-2)</p>
<p>^ should’nt it be (-2,-3)?</p>
<p>Oh, wow. I can’t even remember the answer I put except that it was negative integers.</p>
<p>So, what’s the consensus on this particular test? Hard? Easy? I don’t know what to compare it to since I didn’t really prep for it.</p>
<p>^yea thats what im trying to figure out. what do you all “experts” think the curve will be?</p>
<p>IMO, this test was somewhat easy.</p>
<p>yes user2134, that’s what I meant (on the circle problem)
In my opinion, this test was just ok. Not too hard, not too easy.</p>
<p>3 omitted, 1 wrong so far
come on, 800 !</p>
<p>does anyone remember any other questions?</p>
<p>I think I missed that ordered pair reflection question. :(</p>
<p>I’m at 2 omitted, 2 wrong.</p>
<p>OKAY</p>
<p>(3,2) goes to (-3,-2)… stop arguing… im right
WHERE R U GETTING -2,-3 FROM??? i really dont kno !! heres how u do that problem…Since you were supposed to reflect it over y=-x u do two main steps… FIRST!!! you reflect Y over x=0, which brings it to 2. THen u reflect X over y=0, whcih brings it to -3. … so u plot the point(-3,2) BUTTTT THI POINT IS STILL ON TEH ORIGINAL SIDE OF THE LINE!!! SO YOU NEGATE THE X!!! THE FINAL ANSWER IS (-3,-2) which is to the left of y=-x</p>
<p>THE PERIOD IS 3… the first one the period was 2 and the second the period was 1… THUS the period…</p>
<p>
</p>
<p>The period is 2.</p>
<p>yes it’s 2</p>
<p>and it has to be (-2,-3), draw it and see for yourself</p>
<p>I don’t mean to argue… but I just looked up translating a point over the line y=-x and it says that (x,y) becomes (-y,-x)… which would leave the answer being (-2,-3)</p>
<p>I wish you were right about the point reflection thing, JonLouis, but I’m sure that’s wrong. (3,2) -> (-3,-2) is probably symmetry over the origin, not y=-x.</p>
<p>Some people have confused a reflection about the origin with a reflection about y=-x. If the original point was (3,2), then it is (-3,-2). On a piece of paper, draw y=-x and (3,2). Then turn the paper so that the line is vertical from your perspective. Plot the point on the other side and realize that it would be (-3,-2). TRUST ME I AM 110% SURE.</p>
