<p>I personally think if understood correctly, washer is easier than shells but that is just me. My teacher never taught us shells but I learned it on my own. </p>
<p>Anyway, im still having trouble with related rates and some tough implicit differentiation, meh. Im great with area under a curve and velocity/acceleration problems, but related rates always seem to drive me insane.</p>
<p>do we need to memorize the hard derivatives and integrals such as:
derivative arcsin = 1 / root (1-u^2), arctan, arcsec
antiderviative tan = -ln|cos|u, cot, sec, csc, du/root(a^2-u^2), du/(a^2+u^2), du / (u root(u^2-a^2))</p>
<p>Are diffeqs, slope fields, and series on AB?</p>
<p>Can someone explain Langrange remainder/error for power series?</p>
<p>The Lagrange remainder is basically everything else that isn't included in the terms that have been listed. Just memorize the formula (or put it in your calc). Usually you are asked to find how many terms you need to have an error less than a certain amount.</p>
<p>slope fields are only bc i do believe</p>
<p>is there any specific formulas we need to know or is it given on the test? May be volume of cylinder or sphere for related rate problems? And the idea of putting it in your calculator is a bad one since half the test will be done w/o calculator.</p>
<p>You get volume formulas I think, but no calculus formulas.</p>
<p>anybody know what the curve for calculus is?</p>
<p>Wasnt slope fields on 2005 AB??!</p>
<p>What about arcsin/arccos/arctan derivitaves? Because I'm having a real hard time memorsing them and my test is less than 12 hrs away (that's including sleep time!)</p>
<p>yes slope fields are on AB</p>
<p>it'll help if you know those derivatives</p>
<p>My test is exactly 12 hours away. oops....</p>
<p>shells are not required but from the free-response that has been released, it can save you from doing some nasty manipulation of functions.</p>
<p>P.S. cylindrical shells are cooler anyway. :-P xD</p>
<p>What should we be focusing on right now then? </p>
<p>My friend told me washers/discs/shells only appear on like 1-2 problems.</p>
<p>yikes. im so scared for the testtt</p>
<p>For 2003 it was 68 pts for a 5, around 47 for a 4 and like 30 for a 3... Man, they really had no hope for us</p>
<p>last year's AB definetly had a disc/washer free response problem</p>
<p>I'm praying for a slope-field / separation of variables question. We know a rotating volume question will be on there, but I hope its easy (aka...not revolving around a line above the axis)</p>
<p>Wow that curve is pretty generous.. Is that for AB and BC?</p>
<p>how many MC and FRQ are on the test?</p>
<p>what exactly do we have to know about vectors for bc? we barely covered them in class.</p>
