<p>Hi all,
I decided to start this thread so that those who’ve finished the test can discuss the q’s!</p>
<p>Overall, how hard do you think it was?</p>
<p>Did you take the May test? if you did you probably are aware that the may test was significantly easy compared to other tests which makes me thing that June test is going to be hard…</p>
<p>Just took it. I thought it was pretty easy.</p>
<p>It was very hard test.</p>
<p>I thought it was quite easy as well…what did you guys get for sin@ = x^2 , sin2@=?</p>
<p>lol if you are uncertain about that whole test really wouldnt be easy for you…</p>
<p>2x^2(1-x^4)^(1/2)</p>
<p>Was there any hard probability question??</p>
<p>what did u guys get for the ((1/n-1)-(1/n) Question? was the answer like 2+ (1/n(n-1))?</p>
<p>I got 2-(1/n)</p>
<p>how lol? the fifth term would be 1/4 - 1/5 which would be .05 and the only thing that would give u that is the thing i just said</p>
<p>I wasnt unsure I didn remember what I put in that’s why i asked and thanks for reminding I got that as well</p>
<p>@dino</p>
<p>It asked what the whole thing would equal, not just the last segment of the whole expression.</p>
<p>I put 2-(1/n). Everything cancels out with each other except two 1s in the beginning (which add up to two) and the very last fraction which is subtracted, which is 1/n.</p>
<p>Also if u guys realized the series would never exceed 2, so addition is definitely the wrong solution to this problem.</p>
<p>@Mathgeek +1 thats how I got it</p>
<p>I have a question. Can someone tell me what the question with the circle and we had to find the length of chord AB in terms of theta? Also, what was the answer?</p>
<p>@mathgeek
i got 2sintheta.
what did you get for n(n+1)n+2)?</p>
<p>What did you guys get for questions 49 and 50 (laser one) ?</p>
<p>@etienne
yes it was 2sin(theta)</p>
<p>@mickey
49 was t >= 3</p>
