<p>Here is what I'm wondering:</p>
<p>Hypothetical AP FRQ Question:</p>
<p>Part A - Find the first 4 terms of the Taylor Series as well as the general term.
Part B - Determine the radius of convergence.</p>
<p>Let's say one makes a careless mistake on Part A and misses it. Then on part B, one applies the ratio test CORRECTLY BASED ON THE INCORRECT ANSWER FROM PART A.</p>
<p>Would one still gain points for using an incorrect answer from an earlier part correctly on a later part?</p>
