So... Two days till the Calc BC...

<p>Ok. it's Sunday. and I have realized that I"m utterly screwed for the Calc BC AP.... I currently own a REA review book (haven't looked at it), and two past released APs (frustrating the heck out of me). </p>

<p>What can I do? I really want to try to get a 5. Can you give me some advice? thanks</p>

<p>I'd say the best thing you can do at this point is to go over the two practice tests you have taken & from that.. you should learn a lot of new things!</p>

<p>Good luck!</p>

<p>wut really frustrates meis that....when i take the practice exams, i blank out and dont do good but when we go over them in class, its actually not that hard so i feel lik kicking myself
wut really stresses me out is that we stil get a hell lot of hw and its not helpin cuz it seems like i never have tie to review on my own =/</p>

<p>my calc test is on wednesday too...good luck to ya! i would be really hapy if i PASSSED wit a 3</p>

<p>sun<em>surf</em>N_sand, I AGREE WITH YOU TOTALLY.
I spent most of this weekend doing a US History assignment that I doubt will help me at all for my test on Friday. And I can't afford to spend any more time to study for US Hist (I'm taking 5 exams). </p>

<p>And that happens to me in class too. It's like "ugh, why didn't I think of that?"</p>

<p>Does our Calc BC score take into account how we did on the AB part or is it based solely on our performance on the BC material? Is the AB material included just so that we can be given an AB subscore? Basically, if our grade for BC is based off AB AND BC, I'm saved because I know AB like the back of my hand but I only know about half of BC well. So...any idea? Thanks!</p>

<p>ahahaaahh i juss took an AP PHYS B practice this saturday and it was depressing...i got 18 right out of 70 on the MC
i juss didnt want to be in class on a saturday..it really kills my spirit
so wut i decided to do is to concentrate only on getting a high score on my AP ENG LIT exam ... thus SCREW THE REST (calc and phys) xD
i noe, bad attitude.....blah</p>

<p>what percentage do we need to get a 5 on calc bc? and is the bc portion of the test based soley on the bc material or does it include ab stuff too??? thanks in advance!!</p>

<p>I heard it was 60-65%.
It will include AB stuff too, because you get an AB subscore.</p>

<p>Juniorinhs, To get a 5:</p>

<p>1) Review all your old tests from calc class
2) Review your old notes (spend time on those topics you have trouble with)
3) Do nonstop practice tests from your review books (I would recommend Barron's...its good for math)
4) the day before the exam...do the real practice tests (doing tests over and over is the only way to get rid of careless mistakes)
5) Get your hands on old Part IIs and pummmel them (remember one question will always be on lagrange, series, etc)</p>

<p>Do you think Lagrange will be on one question this year?</p>

<p>hope not. even my teacher cant understand it. I think I'll just skip that question.</p>

<p>woah, I've never heard of that?! wth is it?</p>

<p>I'm sure there will be polar or parametric.
I think it mgiht be parametric this year.</p>

<p>wait are you talking about lagrange error bound or lagrange multipliers?</p>

<p>lagrange error of course.
will it be on there?</p>

<p>I hate lagrange error.
That's confuse me a lot.</p>

<p>Anyone want to explain what it is. Does it have to do with the next term in the series?</p>

<p>never heard of lagrange before. so screw it</p>

<p>The Lagrange Error Bound tells you that the absolute value of the difference between the actual value of the function and the value that is given by the Taylor series at the nth degree, is equal to or less than the (n+1th) degree of the Taylor series. In other words, it tells you how accurate your Taylor approximation is.</p>

<p>The hard part of doing it is actually doing the (n+1)th derivative... For instance, no one enjoys doing the 25th derivative of anything (I remember a practice BC free response that asked for something like this...) the trick that people who are good at this know, is that there is always a pattern to the Taylor series, usually involving a factorial. Once you've listed the first 3-4 terms of the Taylor series, you should be able to identify a pattern for the nth term. That's how you find the Lagrange error bound.</p>

<p>Basically, what I have learnt is just:</p>

<p>Error= f^n+1 (c) * x^n+1 / (n+1)!</p>

<p>where C make the error become the largest error.</p>

<p>That's all I know.</p>
