<p>kaidan do u remember the question</p>
<p>It was airplane with 37 degrees at one town, and like 27 degrees to the other town. Height was 8 and find the distance between the 2 towns.</p>
<p>oh i omitted that one</p>
<p>What was the one about how many times 4 appears in the given list? The answer choices were 0,2,3,4,5.</p>
<p>jhjun: I am unable to remember the question you are talking about, more details?</p>
<p>Kaidan: If you remember the given values I can tell you. Though it was a fairly easy question.</p>
<p>hkim0713: I had no idea what that question was asking and omitted that question.</p>
<p>I thought it was a really easy test, I omitted one because I thought it was a test error but I just misread the question. I think I can get a 49/50 on this one.</p>
<p>it was a recursive sequence question and it asked for the first five terms of the sequence.</p>
<p>the expression was an=a(n-1)+3 i believe and it said n>3 and a1=3</p>
<p>actually it said n>1 my bad not n>3, did we need to include 3 or start from 6 for the first 5 terms</p>
<p>include 3 as the first term</p>
<p>semaphore do u think the test error was the one that said (0,2) when it was really (-2,2)</p>
<p>jhjun: I remember than one. The second part of that question asked for an expression for the nth value of the sequence, the answer to which was x^2 + 2 if my memory serves well.</p>
<p>sema do u think the test error was when they said the interval was (0,2) while it was actually (-2,2)</p>
<p>@jhjun798 are you sure it said for n>1? I can’t remember…</p>
<p>“semaphore do u think the test error was the one that said (0,2) when it was really (-2,2)”</p>
<p>I am curious about this too. I think it was definitely an error. Because question asked for “all” possible values as far as I remember,</p>
<p>Yea thats the right one rohit, can you answer my question about the airplane one? Also i thought it was (-2,2) also but i guessed (0,2)</p>
<p>yes it said n>1 so im wasnt sure to include a1, which was 3, in the list of the first five terms</p>
<p>yea that was question 49…i just put (0,2). as for the airplane question, you had to do tan (theta) = height/distance for both of them…and then subtract the two distances…i got 5.82 or something (answer E)</p>
<p>ugh then it prob meant starting at n=2</p>
<p>Kaidan: I am pretty sure you remember the angles wrong I don’t think both ended in 7. I don’t remember the answer.</p>
<p>The procedure was simple, </p>
<p>(the distance of a town from the point directly below the plane on the ground)/height(8) = tan (angle of depression for that town)</p>
<p>Find both distances and subtract.</p>
