<p>^^ YAAAY lol</p>
<p>fa-la-lena, im taking ap calc as well, and half way through the test i suddenly wanted integrals to turn up!</p>
<p>no it said at what time t does the ball hit so and so after reaching the max. I can see the confusion, but t is the x axis. t has to be 2.5, cuz 2.5 at the x axis corresponds to that. What about the sinsquaretheta/ cossquaretheta question? I put 1...</p>
<p>Kevinscool - it's sec^2 theta</p>
<p>Howd u get that? I was looking at it and thought sin/cos or cos/sin (i forget now) = tan/cot. But if u -1, it couldnt be equal to that? So i thought 1 was the only possible answer</p>
<p>werdddd tangent identity.</p>
<p>1 + tan^2(x) = sec^2(x)</p>
<p>wow what a stupid equation lol.</p>
<p>we're all rather frustrated with this test...argh!</p>
<p>keviniscool - i thought the question asked after the ball reaches its peak, how long until it is twenty feet in the air? it reaches the peak when t is 1.5 and it is twenty again when t is 2.5? or was the question something else?</p>
<p>that was it. so the answer was 1 because it asked for the time AFTER the maximum point. I think I might have bubbled in the wrong answer =(
how can some of you still be fighting that the product-slope question answer was -1/7? two slopes were negative, one was positive. the points on the triangle were (0,0) (3,3) and (7,-1). has to be positive.</p>
<p>I think I did well; crossing my fingers for a raw score of 45. I didn't omit any, and I know I got two wrong, probably one or two more due to slopiness.</p>
<p>i really hope the curve is low
cmon 40 for 800!</p>
<p>ok i forget the wording. I thought the question said at what value t does the ball hit 20 feet or something after it hits its maximum, as in the 2nd time hitting 20 feet? Any1 know the exact wording? ANd i could have sworn there was 1 negative, and 2 positive for the slope? Or i might have actually put 1/7 i honestly forget. Nevertheless, u figure out slope, multiply...it was pretty simple</p>
<p>i can't seem to remember if the bottom slope was 1/7 or -1/7. I know I put -1/7 for that same problem, but who knows...none of us seem to know for sure either.</p>
<p>I remember taking a mental note that the triangle had two lines of negative slope and one line of positive.</p>
<p>Lets stop arguing. Who cares........ its just making us freak out lol</p>
<p>I was retaking this one in hopes of getting a higher grade, but I was utterly shocked. This one seemed way harder than anything I've heard of or taken, and I left like 8 blank because I either simply didn't know how to solve it or didn't have enough time to.</p>
<p>Ahh well. Cross our fingers for a huge curve.
By the way I got 1/7 for that question.</p>
<p>vivi i retook this one for a higher grade too...i couldnt even finish the test this time! bah!</p>
<p>Was it the product of the slopes? I thought it was the sum of the slopes. If that's the case, I got it wrong.</p>
<p>do you guys remember the one about the age of dogs and that CRAZy equation like 0.01122x^4...., i graphed it on my calculator after struggling for a while with it and i got the max so tht means that the age of the dog starts decreasing after 6 years? aah i dont know
and yeah the f(g(x)) one was 2???</p>
<p>^^ that f(g(x)) sounds familiar....</p>
