<p>discuss.</p>
<p>i definitely did the test and then found out the curve for level 2 is much better… oh well.</p>
<p>The curve is typically worse for math II, but the test is also more difficult. I took math I and thought that it got fairly difficult towards the end. Are there any specific questions anyone wants to bring up?</p>
<p>idk, when are we allowed to discuss the answers?</p>
<p>Now. Most threads discuss the answers.</p>
<p>Its amazing the difference in posts between math I and II. Sooo, what did we all think? I think the curve should be pretty standard: 700+ would be like a 40 or better probably. Any particular questions? What did everyone get for the one when it asked how many times point P would touch the bottom as it rolled to the end of the diagram? I think i said 2 times.</p>
<p>yeah its two times because it rolls a distance of pi the first time it touches and then 2pi next time, which is 3pi total rolled, which is ~9 so it cant roll another 2pi to touch again</p>
<p>edit: d was two right?</p>
<p>edit2: what do you think the top of the curve will be? will -1 be a 790 or 800?</p>
<p>Hey, I think it was 1… Coz the diameter was 2… So circumference becomes pi x d = more than 6. So by 2nd the time P touches the ground, it would be well past 12. And if I remember correctly, 10 was the max distance. So there u have it, its 1!</p>
<p>What about the tetrahedron question? By what factor would the Surface area increase if the sides were doubled in lenght? I think its 2…
I HOPE THE SCALE IS GENEROUS, -1 = 800! :D</p>
<p>the tetrahedron one was 4:1.</p>
<p>and the hoop one was 2 because it only rolls half a diameter before it touches</p>
<p>Yea i also got 4:1. and i agree with 2 for the circle question.</p>
<p>Whats the explaination for 4:1?</p>
<p>just take an arbitrary tetrahedron, find the surface area, then double the side and find the surface area</p>
<p>what did you guys get for the one where one of the answers was “not enough info given”? I think it was asking for x^2 + y^2. And it gave you the lengths of two chords in a circle to be 7 and 3 i think.</p>
<p>58 b/c its 7^2 + 3^2 = diameter^2, and they both had the same hypotenuse which was the diameter</p>
<p>unless they didn’t give the angles, in which case I got that question wrong</p>
<p>i dont think they gave the angles. Thats why i put not enough info. But i’m not 100% sure about the angles. Does anyone else remember that Question?</p>
<p>I didn’t do any practice tests (stupid, stupid, stupid - so swamped with school lately), but, for the most part, I was breezing through it until I got to about question 40. Then I had to quickly select which ones to spend the remaining time on. I left quite a few of these last 10 blank :/</p>
<p>Even though the Math II curve is more generous, I’m glad I did Math I. Just looking at the Math II questions in my practice book the night before made me realize how poorly I would do on it. Are you guys glad that you took Math I instead of Math II? If you took both, which one do you think you did better on?</p>
<p>does anyone remember if they gave the angles for the x^2 + y^2 one?</p>
<p>I took Math I and I kind of regret it. I’m in 300 Calc right now, so the stuff that was on Math I was from a long time ago…and I didn’t prep (yeah I’m stupid) =/</p>
<p>wait it is 58 b/c both the angles are attached to arcs of 180 degrees b/c theyre on the diameter –> the angles are 90</p>
<p>at least i think it was a diameter</p>
