me too jyxi!
ok fine, no one accepted
lemme try it
you can the people who are gonna be infected (patients) using the following
i can divide for x ∈ [1 , 2] on a N sub-intervals
every sub-interval has a - Δx wide -
i can have some sample points on the middle of every sub-interval ..and those receive the name of - Xi* -
knowing a bit of area and circles i can get some new data like this one
i can assume F(x) (mentioned on the quoted post) as a constant on every sub-intervals i have made..you can get how many patients i can get on the selected area [1,2]
so patients are "P"
P = π [(Xi)^2 - (Xi-1)^2] F(x)
P = π [(Xi + Xi-1) (Xi - Xi-1)] F(x)
having this i -probably- can get the exact number of patients
on this way
-------------n
Lim---------Σ π (2Xi*) F(x) Δx
n->∞-----n=1
this (finally) give us the integral
2
∫ π (2x) (sin^3(x)) dx
1 --------------------
---------------x
simplifying
2
∫ 2π sin^3(x) dx
1
---2
2π ∫ sin^3(x) dx
---1
I=∫ sin^3(x) dx
I=∫ sin^2(x) sin(x) dx
I=∫ [1-cos^2(x)] sin(x) dx
calling u= cos(x) ___ -du= sin(x)
so
I=∫ sin^3(x) dx = -∫ [1-u^2] du = -u+(u^3 / 3) + C
c is any constant (you can call it monkey or bear or sally or banned or what you want)
we have mentioned u=cos(x)
so the solution is
I=∫ sin^3(x) dx = -cos(x)+[cos^3(x)/3] + C
this give us the answer for a indefinite integral but ours is a definited one (so the constant will say bye this time)
-------------------------------------2
P= 2π [ -cos(x)+[cos^3(x)/3] | ]
-------------------------------------1
P is---
P = 2π [ ( -cos(2) + (1/3)cos^3(2) ) - ( -cos(1) + (1/3)cos^3(1) ) ] = 6
around 6 patients we can get in the mentioned area and 6>4 so .... yes, the quarantine declares
now you can sleep on my serious (and probably pointless) post ...zzz...
(probably some typos are into the big paragraph, not my native language, i speak the language i have created -ill-call-it-'rescrove')
black letters are my secret...lies!!! but i dont care
now i wonder if i made a mistake around..... feeling nervous
All of that for 6.
Psh.

Now I'm sure that there are many jobs that require you to know how to do very complex math...But seriously :|
I have a boyfriend finally.
Go **** yourself society. <3
Also found out:
Chafing.
Sucks.
So.
Much.
I thin i have like 12 different personalities
Im serious , i found the last one on the weekend
The ban is strong with this one.
i have a spot of some sort at the back of my neck and it's so akward to reach around.
who wants to pop it for me?
My breath smells so bad of garlic.
Not even my dog will kiss me.
