<p>ya, do you think i will lose a point if i put the radius of convergence instead of interval, but kind of explained it. i am not sure how many points it is worth, but that was a stupid mistake, i did not read what they wanted…lol.</p>

142

<p>^ could it be possible that the whole quantity (x-1)^2 is x ?</p>

143

<p>I got worked out solutions, if anyone is interested. Enjoy</p>

<p>Just double checking…it was fine to write in pencil, right?</p>

145

<p>Anyone?</p>

<p>10char</p>

146

<p>^yes,i wrote with pencil last yr on the AB, and did the same on the BC last week :)</p>

<p>marcus that is awesome!
im not sure how they will mark my #3, i forgot to let derivative =0 for part a but everything else was right…</p>

<p>Okay, I know I probably shouldn’t worry about what has already passed but…
Suppose I left 8 on the MC blank.<br>
I guessed on 7 of the 37 I answered; let’s say I got 10 wrong total. 37-10=27-2.5=24.5*1.2=29.4. </p>

<p>Let’s say I got 3+6+8+3+4+4 on the FR’s.<br>
Which means a 57.4, assuming I did as horribly as I did. </p>

<p>Is this still maybe possibly a 4?</p>

149

<p>^ 57/108 is a low 4</p>

<p>The overall FRQ was good except #3. Yay for over-thinking I guess.</p>
