<p>Um for the Calculator section of the FRQ there were 4 possibilities she gave us,

  1. Area/Volume Problem
  2. Table of Values problem (estimate derivative at point, Riemann sum, max min, rate, IVT, MVT)
    3)Similar to #2 except it is a graph (max/min, tangent to accumulation function, values of accumulation function using FTC)
  3. leaking at a given rate and filling at a given rate function (rate of change, volume at given time, using FTC)</p>

<p>Non-Calculator 5 Possibilities

  1. Velocity Graph of Motion (don’t need to list things for this one)
  2. Differential Equation to solve by seperation of variables (slope filed, Eulers Method)
  3. Given f and f’ (equation for tangent, critical values, concavity and P.O.I)
  4. Numerica Data of Rate Function (linear approximation, Riemann sum, FTC, acceleration calculation)
  5. Composite Function (find first and second derivative, tangent line)</p>

<p>Thanks a lot Virginiafan.</p>

183

<p>^ Cool, thats what I’m expecting too (they’ve been around the same topics for a few years now).</p>

<p>Barron’s has some crazy problems in its practice tests…anyone tried them yet? If the real ones are like this, I’m screwed. Well I heard Barron’s tests are harder than the actual AP so hopefully I should be fine, lol.</p>

184

<p>My teacher said that shes not sure but thats her best guess based on what they have done over the past couple of years.</p>

185

<p>I’m freaking out!! 10 hours until the test. =/</p>

186

<p>Someone confirm this:</p>

<p>d/dx [g(f(x))] = g’(f(x)) * f’(x)</p>

<p>Right? I’m blanking out…</p>

187

<p>

</p>

<p>can someone help me solve the two problems above, please?</p>

<p>@AxeBack: i think so. they’re kind of the basic plane shapes.
@aznjunior: you look at the graph and find where f’(x) = 0. in order to know if those x-values would result in a min or a max, you have to plug those x-values into f(x), so if you’re not given the function for f(x), you can just know where f(x) gets its extrema.</p>

<p>I have seen a differential equation and find the area/volume of solid generated on every practice test i have taken</p>

190

<p>I absolutely hate the Non Calculator Multiple Choice section of the exam =(</p>

191

<p>can someone explain to me the 2008 free response question 1c
<a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;

192

<p>Wait, so is it predetermined that we either get Form A or Form B? Or is it random?</p>

<p>Form B Free response looks about 10 times harder…</p>

<p>@ koreanxpanda</p>

<p>So the area of a square is x^2 right?</p>

<p>Now all you do is plug in the R you got in a for x and voila! Same thing with circles (plug R in for pi*R^2) and other shapes.</p>

<p>A lot of people get confused with these problems and I don’t know why. Make sure you don’t use pi in it (thats where a lot of ppl mess up) because it’s not revolving around anything - it’s just a square. Try to visualize it and you can see that it’s oddly shaped square like block.</p>

193

<p>You get both. And yes, form B was much harder.</p>

194

<p>We don’t get both…I hope you know how many problems are on the Free Response.</p>

<p>That’s 12 questions lol</p>

195

<p>are there a lot of exponential growth/decay questions?</p>

196

<p>^ Most likely one FRQ, and it’ll probably be in differential form. You’d have to solve it first, then use the exponential model to estimate stuff and…things…yeah.</p>

197

<p>edit: nevermind</p>

198

<p>greeeeeeeeeeeeeat…i hate exponential growth…i hate calc actually</p>

199

<p>You guys should get some sleep.
Morning session. x_x</p>

<p>

</p>

<p>Agreed .</p>
