you posted a roach

I want to show that not all open balls of (Z,d) (with d being the discrete distance ie d(x,y) = 1 if x=/=y and 0 otherwise), are not connect spaces.
You take B(0,2[ = Z and therefore this ball is not a connected space because (Z,d) is not a connected space. (because you can find parts of this space which are open and closed other than the empty set and Z.
Is this the correct reasonning ?

do you even know what P and NP are? give me a prime factorization algorithm that's in P time.

>>8521388
only if P=1 or N=0

People start getting together to discuss how our so called leaders are actually fucking everything up and the world becomes a much much greater place in a matter of months. All bad people are stripped of their power to control people and rehabilitated to be good people and we continue to discover our possibility of liberation or freedom through awareness and consciousness. Or they destroy that possibility for the near future by increasing the magnitude of the systematic destruction of the masses lives.

>>8521337
Digital waifus existing and you can have as many as you want wherever you go.

All I ask of the singularity since I'm tired of dating.

You gotta compute the derivatives and then manipulate them to get the expression of [math] da/dt [/math].

>>8521167
Ok so da and dt here are just da/dN and dt/dN
So just compute derivatives of a and t with respect to N ? Is it normal to write da and dt and it meanda/dN, dt/dN? I mean it should be obvious I'm differentiating with respect to N since its the only variable but it triggers my autism a little

>>8521158
Well you're given a in terms of n, so just take the derivative with respect to time (I'm assuming A is constant):
da/dt=(A/2)*(sin(n))*(dn/dt)
Now, to solve for dn/dt you need to take derivative of the time equation with respect to time:
dt/dt=(A/2)*(dn/dt-cos(n)dn/dt)
dt/dt is equal to 1, so solving for dn/dt we get (2/A)/(1-cos(n)). Plugging this back into da/dt we have
da/dt=sin(n)/(1-cos(n))

Yes, highly likely that it is.

>>8520841
Wrong. Only a theory until proven true.

Yes to both.

which shitty colleges do this? i got to pick all the courses i wanted aside from mandatory ones that are prerequisites for all the higher level classes in my major

Noone takes life seriously anymore.

Our culture is fucked and i think the "well-rounded student" is a good idea.

what?

So no, definitely not 27 nuclear bombs - it's about a billionth of one, in fact.
It is, amusingly, quite close to the approximate energy content of half a cheeseburger.

>Thats 27 nuclear bombs as it hits the atmosphere.

What the fuck kind of calculator are you using to get that kind of result?

>>8520737
One little problem with your calculations. You specify that it hit the Earth. That means you have to take into account air resistance.

no

especially not if you're here shitposting instead of doing exercises

lmfao

Okay guys be gentle. I'm not a brainlet, and I attended class for the first month and a half. It is a hard class though :( Pls post interesting theorems

Nice arbitrarily chosen group of characteristics

discussion isn't opposite to facts and sources.
also most scientists care about society and avoid the ivory tower stereotypes, at least to get a better image

goddamn. well it's certainly going to take you a good long while. I'd say at least two years. if you are TRULY going to learn this.

there's a bug gap between that and general relativity
you need to understand Riemannian manifolds

It's probably a cosmic ray of some kind. If it was anything real it would show up in SDO/AIA but it doesn't.

>>8520594
Are they the same type of camera? It's still very strange for me, the idea of a cosmic ray is something strange, I have not the slightest idea of it, but it is interesting (outside of ayylmao, whatever provoked it is rare, in my opinion)

>>8520506
There's are these places known as "ewneeberhseetees" that I think will do.

Sorry if I spelled it wrong, it is just that these places are so underground that literally nobody even knows about it. So underground people have to come to a chinese cartoons discussion website to ask about them. So underground man.

>>8520506
If you're retarded at math, then you won't be able to understand probability and statistics enough to remember and utilize the concepts.

Math is something you build off of. Go on KhanAcademy and start by learning the part of math that you need competence in. Go through the Precalculus module on there. After you complete that then start with some calculus books.

how is it that even with the internet people dont know how to find one of the thousand textbooks on a subject they're interested in?
