<p>what are you guys doing right now?</p>
<p>last year there wasnt a BC calc class, and the teacher who used to teach it left. so this year is the first time my teacher is teaching BC...and i think we are REALLY far behind. like ridiculously behind.</p>
<p>ahh idk what to do. im gonna be screwed for the exam. i guess it doesnt really matter tho haha.</p>
<p>We just started slope fields and differential equations today
Prior to that we learned derivatives and their applications, reimann sums, integration(definite, indefinite, substitution)</p>
<p>whoa...we did slope fields a month or so ago.</p>
<p>right now we are doing rational functions and partial fractions within an integral</p>
<p>christalena-what other major topics have you done already?</p>
<p>haha i have no idea wat a slope field is.</p>
<p>but we are like working on u substitution in intergration, pretty far behind.</p>
<p>slope fields are graphs where small lines on each numerical unit represent the slope...and depending on what function you have, you just...pretty much connect the dots. It was the easiest thing to do this whole year so far. </p>
<p>Do you mean integration by parts? Where you find u, and dv, and depending on what the equation is, you take the derivative of one part and the antiderivative of another? If yes, thats not far at all! That was the last lesson of the semester, and we've only had two more since then. Maybe your teacher didnt cover slope fields cause he/she thought that he could skip it because it will probably not be a huge part of the exam.</p>
<p>idk maybe we just didnt call them slope fields? haha thats seems kinda familiar.</p>
<p>well we havent finished our first semester. its done on friday, we have a kinda wierd schedule.</p>
<p>yeah i think thats what im talking about, you just pick something to be u and then you find du and sub it in and find the intergral..haha its hard to explain.</p>
<p>oh ok...if you are at the end of your semester, thats not bad at all...i think we were one lesson past what you are learning now (maybe youll learn it within the next few days) by the end of our semester. You sound like you are in the right place though, no worries.</p>
<p>We're doing indefinite integration, volumes (washer and cylindrical shell methods), and length of curves.</p>
<p>Just finished the chapter about volumes (shell, washer) and s, S.</p>
<p>my class just started 3 days ago, and we just covered integration by parts, trig integration (by parts). we have semester classes. so you can't be farther behind than our class....its our teacher's first year teaching too, but he's not too bad.</p>
<p>EDIT: hmm just read some of the posts and we did all of that in AB (the washer shell stuff, slope fields, indefinite integration, all of what crosscurrent mentioned). i guess we're not too far behind then =/</p>
<p>Applications of definite integrals.</p>
<p>We did washers a while ago too....i guess our class is going REALLY fast....geez</p>
<p>we're taking our volume test today (washers and whatnot), starting integration by parts/l'hopitals rule tomorrow</p>
<p>Slope Fields as well...this is right after u substitution/Indefinite and Definite Integrals/Fundamental Theorem</p>
<p>I've never heard of slope fields, either. Is that by any chance another term for a vector field or the gradient of a function?</p>
<p>We're doing areas and volumes right now. I'm not worried about our timing because I have a great teacher who says we're on schedule, and he always finishes on time. We'll be done with the AB curriculum by Tuesday, plus some BC topics that fit in as we went along. We've already done integration by parts, slope fields, differential equations, etc.</p>
<p>haha yeah so im basically screwed.</p>
<p>for slope fields...go here: <a href="http://www.sosmath.com/diffeq/slope/slope1.html%5B/url%5D">http://www.sosmath.com/diffeq/slope/slope1.html</a></p>
<p>just make an x/y chart for the function. And at (0,0), you draw a line that approximately represents the slope, and then again at (0,1), and again...just look at the site.</p>
<p>... We're on the root and ratio tests for series. =P</p>
<p>Except we covered the AB stuff by doing the chapter reviews for each of the 6 or so chapters that have all the AB material in them. Our school forces us to take AB and BC in separate years, so we just have to cover the BC stuff. =)</p>
<p>"Our school forces us to take AB and BC in separate years, so we just have to cover the BC stuff. =)"</p>
<p>ooh, that sounds better than stuffing it into one year. It's not too terrible, but i got a B last semester (one percent on my final away from an A, so mad. She wouldn't change it for me...got over it though).</p>
<p>But that would mean that you took AB as a junior right? Do most juniors go that route, or do they take more basic math classes?</p>
