<p>2 more days! Good luck to all those taking the calculus tests.</p>
<p>hey, how are you studying for the test?</p>
<p>My teacher gave us review packets I’ve been doing, not much else I can do to prepare in the next 2 days. I’ll probably study the basic integrals and derivatives tonight and tomorrow though</p>
<p>I’m working through problems in my Barron’s book. </p>
<p>Is the curve really generous? Because I’m missing a LOT, and so now I’m praying for a four =/.</p>
<p>its like theres no released exams, and isurus, we took a past ap exam, and it was pretty easy to get a 3. its jsut the 5 that was kinda hard to get. so getting a 4 is pretty feasible</p>
<p>I’m self-studying. I took a practice exam and had 40/44 on the MC, but only a 21/54 on the FRQ. However, my house was Ringling Bros. and Barnum & Bailey during the latter part of the MC and all of the FRQ, so I think that decreased my score.</p>
<p>Can someone help me with this problem I am having?

<p>For number 2 in the FR section in part B, it asks to find the average value over a certain interval. Now I understand the intuition completely behind the problem in that you find the x values that correspond to values equal to 150 but I don’t know how to find the exact values using a ti89. Can someone please tell me how I can find the x values using a ti 89 or even intuitively (ti 89 method preferred since I fail at algebra lolz).</p>
<p>Just graph a horizontal line y=150. Calculate the intersects. Write down the two values of x (all digits), plug and chug. </p>
<p>Also, if you haven’t done it yet, you should upgrade your TI-89 OS. The newer OS has Math Print, which makes typing in integrals and derivatives much easier.</p>
<p>Does anyone know how much of each part of calculus is on the test, percentage-wise? Or is it not based on that at all? I know for history tests at least they divide it up into time periods.</p>
<p>I’m pretty sure its random - but I’d definitely expect optimization, related rates, solids of revolution, and some kind of natural log / euler’s number equation</p>
<p>Yayyy! Calculust tomorrow! Everybody get pumped -______-
My words of advice:
-Take dat test, don’t let it take you
-You have all the knowledge that you need to succeed
-The limit does not exist
-Andddd when in doubt, derive…or get and integral out… :D</p>
<p>Good luck everyone. Get a good night sleep, and I know you all will do awesome[ly]</p>
<p>^ The limit always exists. </p>
<p>When in doubt guess (ln(ln(x)) or (lx(x)^2)</p>
<p>Should we memorize/ learn the formulas of volume and area for related rates?</p>
<p>^^I wasn’t being serious…</p>
<p>eta: and maybe you aren’t being serious? hmm</p>
<p>Okay, this is a serious question: should I review sigma notation for evaluating integrals? I haven’t seen it on a practice MC or old FR question, but we all know what that means… Has anyone’s teacher said anything about it?</p>
<p>^ That isn’t even hard, but no need of memorizing it.</p>
<p>So how really generous is the curve? Anyone know how many MC/FR do we need to get right to get a borderline 5?</p>

<p>I don’t know how accurate it is though.</p>
<p>^ yea I already saw that, but it gives too much leeway to a 5. According to it, you could get -4 wrong on each FR and 15 wrong on MC, and you could still get a 5. I am asking if anyone knows about the score scale based on the past exams.</p>
<p>My teacher says a 5 will be about a 68/108, so that’s like getting 30 multiple choice right (the multiple choice are multiplied by 1.2), and a 32 on the FRQs (which would be 4 5’s and 2 6’s). something like that… it depends on whether you’re better at frqs or mc’s</p>
