Re: Learned League 72  Official Thread
I don't understand why the math question had such a low getrate. There's no time limit so just plug the numbers in until you get it...and it comes out to 2.7

Re: Learned League 72  Official Thread
Yep! Didn't even bother to plug a number in because, as someone else pointed out 3.1 on Q4 just works so well. My math stats pretty much guarantee me a 0 defense, so I would have lost either way.georgespelvin wrote:I was totally clueless on the Math question (as I almost always am), but thought that I was being clever by guessing Pi because of what day it was. My instinct on this was so strong that I even marked it as a two instead of a three for my opponent who was one for eight in Math (it did not affect the outcome). Anyone else out there guess Pi because yesterday was 3/14?

Re: Learned League 72  Official Thread
Agreed. I think it just looked so daunting lots of people didn't even bother. Of course you'd also need to know what the notation "lim n > infinity" meant.cf1140 wrote:I don't understand why the math question had such a low getrate.

I was shocked to discover that my opponent with a .714 on Mathematics didn't make the effort to figure this one out. I solved for n=2 and n=3 then realized where it was headed. Before solving and without carefully parsing the question I had assumed it would converge on 0, 1, or infinity. Including the "if expressing the answer as a number" was a very useful hint.

I used to be AWSOP but wanted to be more theatrical.
Re: Learned League 72  Official Thread
I figured it was either 0, 1, e, or pi. The 'nearest decimal' part indicated it wasn't 0 or 1. A few calculations deep and I could see where it was going (though I will say that posing this question on Pi Day was serious negbait).mcsheffrey wrote:I was shocked to discover that my opponent with a .714 on Mathematics didn't make the effort to figure this one out.

Re: Learned League 72  Official Thread
I crushed calculus in high school and college, but sadly don't remember anything beyond algebra and geometry.
Like others, I plugged in the numbers and assumed the limit was 2.7, not remembering the irrational number e or realizing it was Pi day.
Got 1 point for my troubles and a win. Opponent went 0(0)
Went with middling instead of mediocre. How does ocre=mountain?

My math percentage is abysmal. I looked at that question and was going to leave it blank because I have no idea what "lim n > infinity" means, except that I recognized the infinity symbol.This Is Kirk! wrote:Agreed.

But I looked at the equation (if that's the word I want) and thought, "I wonder what happens if I plug in a number and just try doing the math?" So I did n = 2 and got 2.7. Trying it with n = 3 got me into places where I would have needed a calculator to get to the answer, so I quit trying that number.
Then I read the question again and thought, "Mathematical limit? What does that mean? I have no idea. Oh, well, maybe I should just submit 2.7. But that seems kind of simple....wait, today is March 14th. Could this be some other weird way of getting to pi, and I've missed something? That's certainly possible. I'll just put pi."
Hit "submit," and...
Re: Learned League 72  Official Thread
So, as I'm not mathematically inclined, and had no intention of trying to dredge up 20+ year old stale thoughts about how to make the calculation, I just went with this and let it go.
I'm living proof to show that a good attitude, a Southern accent, a ridiculous beard, and a middling amount of trivia knowledge can get you onto Jeopardy!

See my post edit earlier about my opponent's 7(4) becoming a 7(5).

Re: Learned League 72  Official Thread
This is only the second math question I've ever missed. I just read skullturf's solution (posted elsewhere); turns out that Calculus II methods are enough to get close, but you need more highpowered machinery to distinguish (rigorously) between two plausible lines of reasoning that lead to the correct answer of e and the incorrect answer of 2e (which was my answer). If I had calculated the expression for a few more n's, I could have gotten it right.
I was doubly irritated because yesterday was an unusually busy day and I spent some time on that question which took time away from other questions. The good news is that (unsurprisingly) I had been assigned a 0 for that question and I lost 3(2)7(5), so I don't think I was ever going to win the match.

You're too kind. It was I who squeaked out the 4(3)4(4) tie, my first of two in a row (though in the second I got four right). Had I not punted the SaxeCoburg question in our match, I'd have had my firstever tie with identical defense.ElendilPickle wrote:I knew it wasn't O'Keeffe, but that was all I knew.

Re: Learned League 72  Official Thread
I tried solving it analytically, but gave up after a few minutes. This is one question where actually plugging in numbers and seeing where it converges is way easier than the full solution. The problem had already converged to be rounded to 2.7 once you have plugged 3 in the solution. Being a masochist, I did 2, 3, 4 and somehow thought figuring out 10 would be easy (it was tedious).skullturf wrote:Yes, I was going to mention here, just in case some folks are interested: The first thoughts I posted this morning are here and then my thoughts from a couple of hours later are here.Linear Gnome wrote:This is only the second math question I've ever missed.

Or you were me, who didn't start trying to do math until past my bedtime and even simple fractions turned into an enormous mess. If I didn't know Eleanor Roosevelt yesterday, I would have pulled a 0.

Re: Learned League 72  Official Thread
I didn't make it all the way through it, but even 10 wasn't too too hard. It was basically (10/9)^9*10. 10/9=1.11, so multiply that out 9 times. But yes, 3 showed where the convergence was pretty quickly.boson wrote:Being a masochist, I did 2, 3, 4 and somehow thought figuring out 10 would be easy (it was tedious).
