@galaxyexplorer I got like 0.9 for the unit circle one.
@jetnyz the one where f(x+1)=x*f(x)
@galaxyexplorer, ugh you’re right. I ran out of time and thought I got the right answer but LOL i was sooooo wrong. I think its 24 (Lol you don’t even want to know what I put)
@jetynx what you get from unit circle one
@idkName That was one of the two I skipped haha, I’m in AP Calc BC rn and have forgotten all of these tiny things. I should have studied more lol. I also skipped the blood one because for some reason it just wasn’t sticking with me.
What did you get for the 7/8 <_ x <_ 4/3 ?
Btw if its any help, after the timer was over I peered around and saw people had put A for 49 if that helps you
I got 8/11 for that one. In the unit circle, (sin x, cos y) are the coordinates and r * theta = arc length I think you mixed up the sin and cos
@jetynx 8/11
A?i got C =/
Am I the only one that got 3/4 (9/12) It was greater than and equal to 1 right?
I just got common denom and made it 21/24 to 32/24
21 22 23 Are below 1
24 25 26 27 28 29 30 31 32 Are above or at
So 9/12? Idk, what did you guys do
lol I also got the answer for 49 at the last second. So I bubbled it quickly because the instructor is a tough-ass and might consider that “cheating”. So I didn’t bubble it in very well. Hopefully it won’t messes everything up.
@jetynz well never do it by hand. I added 1/4 + 1/8 together, then 1/3 by it. It was asking for all real numbers between it so… Don’t think you can just count the numbers.
@idkname Obviously I don’t usually do things by hand. But for this it was like asking for the ratio of numbers between that would be more than 1 so I used that example to see.
How does ur math work? Why did you just add those numbers and multiple by 1/3. I must be missing something
@idkName: was theta on the left side or right side of the radius?
For the problem with 7/8>=x>=4/3, I got 3/4. Correct me if I’m wrong but to find the ratio of what is greater than or equal to 1, can’t you multiply the first by 3/3 and the second by 8/8 then start listing numbers over 24 that are within this range? After doing that I got that the potential set of x values is 21/24, 22/24, 23/24, 24/24, 25/24, 26/24, 27/24, 28/24, 29/24, 30/24, 31/24, and 32/24. Then, since the total number of fractions greater than or equal to 1 is 9 and the number of fractions that is less than 1 is 3, wouldn’t the ratio be 9/12 or 3/4?
Then again, im not sure, and I rushed at the end.
@idkName
@jetynz Just saw your comment, and i totally agree. That’s what I did
@nearea BAE <3 Ily yay that we got the same answer. I did the same exact thing as ya! <3 
#smiling #yay #imwaytoohappyRN
@nearea wasn’t it asking for probability?
@idkname Would still be the same, a 9/12 chance
You can’t do that. It asked for the numbers in the range. There are an infinite amount. Do ( 4/3 - 1)/((4/3) - 7/8)
@jetynz, no it is asking for all the real numbers in between. You can’t just turn it into a bunch of fractions. Unless I’m missing something from the question.
@galaxyexplorer How did you do it then? But i think probability wise it should be the same ratio of above/at 1 to below 1
