<p>Does anyone know any for sure topics on the AB free response, and does anyone have any educated guesses on the topics?</p>
<p>Good luck everyone! :)</p>

<p>Hard to predict topics for sure, but they’ll usually have a FR question on trapezoid or rectangle rule and approximating an integral, or solving a differential equation, or a related rates problem.</p>
<p>area under the curve, rotation for sure. the rest just pretty much what rspence said</p>
<p>Will there most likely be a related rates? :/</p>

<p>theres a good shot that there is a related rates problem.</p>
<p>Area under curve, no doubt! Maybe a chart and related rates and piecewise, but most likely a graph that is labeled f or f’.</p>
<p>Might be a question on shortest path or minimum cost of something.</p>
<p>Are there usually related rates problems… I haven’t found one on a previous year’s FRQ yet</p>
<p>I’ve done a lot of comparing with the collegeboard tests from previous years, and these seem to pop up a lot…
- Area between 2 curves, volume from rotation, and cross section
- Graph to solve position, velocity, and acceleration functions
- A chart with Riemann sum
- Volume of an object (gas tank, tub, etc.) being filled or emptied
- Position of an object moving on a line and it’s velocity/acceleration
- Derivative and integral of exponential functions
- Related Rates</p>
<p>@imagineer10 Do you know if differentials will be on there?</p>
<p>Yes, I’m pretty sure they will be @pastelblue</p>
<p>@graceann Like with +/- .05, △, etc.?</p>
