<p>I’m glad I have the teacher that I have, because I felt very well prepared for this exam. Only thing I wasn’t ready for was #6 on the FRQ for AB form A with the differential. But that really isn’t her fault, I probably should have studied that harder.</p>
<p>RC, I came across a problem like that in my own preparation for the exam, and I didn’t know how to do it. I asked my teacher and she told me we didn’t have to know that for AB. UGHHH. She also told me that about AB form A #1c. :(((</p>

<p>They are two of the most widely used, but I can think of several authors whose books are more regarded than Thomas & Finney. The T&F calculus books teach calc at a basic level for everyone so they’re extensively used in this country’s colleges and high schools. Spivak, Apostol, and other top notch books aren’t used as much but are regarded much more.</p>
<p>Beta, I don’t remember going over 1C in class either, but I used what I thought was right. Not 100% about it, but I think I got it right:</p>
<p>0 for 0<=t<6
125(t-6) for 6<=t<7
108(t-7)+125 for 7<=t<=9</p>
