<p>There was another one that got revived from 2007 so I started a new one.</p>
<p>Does anyone know what we need to know about differential equations for AB besides slope fields and solving by separating variables?</p>
<p>Goodness. I am so nervous for this test and haven’t been studying at all because of APUSH. But I think that’s all we’ll be tested on for differential equations.</p>
<p>They have some tangent line problems too.</p>
<p>Like, if f(x)=3x+5 whats the line tangent to F(x) at the point (0,5).</p>
<p>(I took AB last year, taking BC this year).</p>
<p>haha same here, i’ve been studying for apush.
have you guys taken a practice ap mc exam?
our class average was 16 right
which is not that good, because youre supposed to get atleast half right to get a 3 =/</p>

<p>I just got a total of 17 right on a M/C section of a BC practice exam and got a 4 on the test. I personally think free response is easier than M/C.</p>
<p>Does anyone have a MC questions (either AB or BC) that I could have? I self studied and haven’t got a chance to look at any official questions. If so PM me.</p>
<p>Is there a standard for grading the free response questions? What kinds of things will get points docked, what kinds of things won’t make a difference and how does partial credit get awarded?</p>
<p>Yes, collegeboard has the AP scoring guideline I believe. Check the AP Central Calc section on collegeboard.</p>
<p>o ya thanks</p>
<p>Hey the answer to the problem is 5= 3(0) + b right? i’ haven’t beens tudying at all. for any of my exams. im screwed. and my first one is tomorrow in frnech. Oh putain, je suis dans la merde!
y=3x+5</p>
<p>Good luck on may 6th fellas. Hope we all get 5’s on our respective tests.</p>
<p>"y=3x+5 "</p>
<p>yep. but don’t be surprised if they throw in some trig into problems like that.</p>
<p>bump 10char</p>
<p>what do we need to know about parametric and inverse function? will there be some really hard questions about these two topics?
i also heard the integration problems are not that hard for AB, true?</p>
<p>There’s a crapload of stuff for parametric/polar/vectors you need to know.</p>
<p>As for inverses, know the derivatives of the arcsin arccos etc. and also
If g is the inverse of f and (a, b) is on f</p>
<p>g’(b) = 1/f’(a)</p>
<p>One more thing
f(g(x)) = x
d/dx f(g(x)) = 1
f’(g(x)) g’(x) = 1
g’(x) = 1/f’(g(x))</p>
<p>what do you mean (a,b) is on f?</p>
<p>For some point (a, b) on f (meaning that (b, a) is on g) that formula holds true.</p>
<p>i am taking AB, so is there still gonna be a crapload of parametric stuff?</p>
<p>No, there is no parametric/polar on AB.</p>
<p>two days until deathday. </p>
<p>hurrah!</p>
