First game :

try to find out which maps these three screenshots come from, you should list all three correct beatmap links, also you may not edit the post.

the first one who post the correct answer will win a modding ticket

Okay here is the last quiz:

49 is a special number so that 49 and 1+2+3...+49 are both perfect square. Find the next number that satisfy this property.

(Perfect square is defined as a number which is n * n where n = 1,2,3 ... )

由x≥0，y≥0，得 y³≥0，x²≥0。
∴0<y³≤1≤x² ∴0<y³/x²≤1
题目中不等式可化为x²(x - 1)≤y³(1 - y)
两边同除x²，得 x - 1 ≤ y³/x²(1 - y)
又 1 - y ≥ 0 ，0<y³/x²≤1 ， ∴y³/x²(1 - y) ≤ 1 - y
∴x - 1 ≤ 1 - y ，即:x + y ≤ 2，得证。
为何这么蠢

makes no sense

I give up

此虽然结果是证明X^3+Y^3<=2的，但是第二步已经证明出X^2+Y^2<=2....

你说答案弱智 我猜是不是这个
x² + y³ >= x³ + y^4 , x > 0, y > 0

it's okay despite not the most simple way :>

a more simple solution:

we have

x^2 + y^3 >= x^3 + y^4, which is

x^2 - x^3 >= y^4 - y^3 or y^3 - y^4 >= x^3 - x^2


also we have x >= 0, y >= 0 , that is

if x = 0 & y = 0 ==> x^2+y^2 = 0 < 2
if x > 0 & y = 0 ==> (x^2 >= x^3) ==> (x<1) ==> (x^2 + y^2 < 2)
same as y = 0 & x > 0

if x > 1 & y > 1 ==> inequality trivially does not hold
if x < 1 & y < 1 ==> inequality trivially hold

if x = 1, y^3 >= y^4 ==>
if y = 1, x^2 >= x^3 ==>

then

if x > 1 > y

1 - y > y - y^2 > y^2 - y^3 > y^3 - y^4 >= x^3 - x^2 > x^2 - x > x -1

we have
1 - y > x -1 ==> 2 > x+y
y - y^2 > x^2 - x ==> x+y > x^2 + y^2

put together, 2 > x^2 + y ^2


if

y > 1 > x

x^2 - x^3 >= y^4 - y^3

similar to above

Two quiz for two modding tickets:

Rules:
  1. You may not edit your post!
  2. There're two quiz in total, the one who posts the correct first will earn a modding ticket
  3. One answer per person, that is , you may not answer both questions , also means you may not both the tickets.
QUIZ #1
Here are THREE screenshot from THREE different anime, post all the correct answer of ANIME Name with SEASON Number & EPISODE Number

Q.2 (just try

if real solution exists, then

x^4+y^4=(x^2+y^2+sqr(2)xy)(x^2+y^2-sqr(2)xy)=z^2, show that the result of formula on the left is a perfect square

but (x^2+y^2+sqr(2)xy)≠(x^2+y^2-sqr(2)xy), and it can't be factorized anymore

so, there's no real solution wpcap 四暗刻 我先回去想想
