<p>^^sin(theta)=theta for small angles.</p>
<p>^I used the analogy route to check my answer, which was really helpful.</p>
<p>^Usually the question will tell you when small angle is needed as in 2009 (number 2)</p>
<p>I might’ve pwned #3. It’s just 1 and 2 that will destroy me.</p>
<p>What the hell was up with the graph sketches this year requiring for maximums, minimums, asymptotes, etc. to be labeled? That’s never been a requirement in the past.</p>
<p>Keasbey - That has all been required in the past.</p>
<p>^It’s never been that specific, though.</p>
<p>Honestly, all that I labeled were asymptotes and initial points (i.e. y-intercepts). I didn’t get any min/max or anything else listed on my graphs. IMO, the test writers seemed to really complicate things this year and stuck both helpful and distracting things in the directions.</p>
<p>Is it cool if i used a least squares regression line from my calculator for the lines?</p>
<p>You’re supposed to select points from the line you draw on the graph in order to determine its equation.</p>
<p>^ yupp that is what i did, you get points off otherwise.</p>
<p>I picked two points that were given . . . uh oh, I guess that’s bad since they weren’t on my line (line of best fit went over/under). AHHH this sucks!</p>
<p>Sooo did anyone else take Bio in the morning, then Mechanics, then E&M? I was basically dead after all that testing. Mech was uber-uber-rapey compared to older mech tests.</p>
<p>dammit all, I guess it’s just 1 point off anyways</p>
<p>also, for 2, were we supposed to graph acceleration or velocity?</p>
<p>acceleration</p>
<p>
</p>
<p>I did Music Theory, then Mech, then E&M. I was dead by the end of E&M; thank goodness it didn’t rape as hard as Mech.</p>
<p>
</p>
<p>Magnitude of acceleration (acceleration was negative, so not seeing “magnitude” tripped me up for a couple of moments)</p>
<p>e^(-t) 10char10char</p>
<p>^Is that what the graph was supposed to resemble?</p>
<p>^ thats what I put basically</p>
<p>What points were we supposed to graph? I graphed from the beginning at point A all the way till the blocked stopped, but I don’t think we were supposed to graph all of that lol.</p>
<p>Yeah, my graph also looked like e^-t for a portion of it.</p>
<p>We were supposed to graph from point D to stopping. Initial acceleration was (-k/m)vD (I think I may have just put vD) and it was an e^-t for the rest of the way, with a horizontal asymptote of acceleration=0.</p>
<p>Just realized that I had asymptotes on all of the graphs on both Mech and E&M. Weird.</p>
