<p>fallen angel. you needed part A for part b…</p>
<p>Hence why I said “but couldn’t do part (b) because I couldn’t figure out part (a).”</p>
<p>FallenAngel9, </p>
<p>I think it’s just an algebra 1 thing.
general form of tangent line is: y - y1 = m(x - x1)</p>
<p>so we know y1 and x1, because f(1) = 2 is given.
so at (1,2) the slope is: (1)(2)^3 = 8.</p>
<p>plug everything to the equation:
y - 2 = 8(x -1)</p>
<p>oh ya sorry didnt see that</p>
<p>Oh wow; I was thinking that the f(1) = 2 only applied to f(x), not the derivative (dy/dx = xy^3). My brain must have been tired. Thanks, I knew how to do it all but couldn’t because I couldn’t figure out where the y-value came from. lol Epic fail and a 3/9 or so.</p>
<p>At least I did part (c). haha</p>
<p>EDIT: ^ No worries, it happens.</p>
<p>On #5, how do you find g(-2)? It’s the only one I missed (except 6b,c).
(AB)</p>
<p>Webass, could you do all of the AB solutions? :p</p>
<p>To answer your question, take the integral from -2 to 0 and add 5.</p>
<p>nah, can’t type integrals and stuff in textarea.</p>
<p>how many points do you think you would need to get a 5 on BC?</p>
<p>Just type intergral between… or just the answer would be appreciated</p>
<p>oh wow.</p>
<p>so is g(-2) = 5 + pi ?</p>
<p>Anybody think the curve for BC might be 65ish/108?</p>
<p>That’s what I got for it, webass.</p>
<p>Ugh, I just realized that I forgot about the initial condition g(0) = 5 on problem #5. Man, what a stupid mistake. I have the integrals correct except for the plus 5. I wonder if I’ll get anything for that, but probably not :(</p>
<p>anyone have the answers or know when i can find them? ! i need a 4 to get into my school its conditional so im nervous</p>

<p>I have 2 more years in high school :(</p>
<p>I keep putting numbers into the AP score calculator and it seems that even with some dumb mistakes I can still make a solid 4, which is what I need. I can manage even with getting a low score on #5, which is what it may end up being.</p>
<p>I think I really messed up on FRQ 1. For my piecewise function, I had a bunch of intergrals. Seemed kind of awkward.</p>
<p>I found a site that has the FRQs solved:</p>
