- probably
- it doesn't matter
- you're wasting time not learning higher level. You don't need mega arithmatic skills.

>>7972825
The only way to do math faster is to do lots and lots of it. Its basically like any other skill.

>>7972825
use a calculator they're more reliable

What is the objective of topology?

when i learn this what am i able to do?

>>7972711
Topology can be thought of abstracting the notion of limits and "closeness" in calculus. It allows you to extend these ideas to in different ways to spaces more exotic than standard Euclidean space.

>>7972723
intersting.

its ionic the diagram is probably showing the lattice structure or something, ironic or covalent bonding is determined by the difference in electronegavitivy

did you even fucking read the book?

Climate change

Another noun, and a plural noun.

>>7972426
Human observers. Quantum mechanics is proof that the universe was made by God for humans.

>>7972428
What if the photons that are emitted when we look at it hit the wave and change it?

>>7972430
In theory it works but in practice it doesn't.

I'm shocked.

>>7972281
It happened, actually...at least the 2010 one

He's a madman dude. He lost his shit in the the 60s trying to come up with the singularity hypothesis.

I can't believe I took the time to read that

He sounds kind of like Steven Wolfram.

>>7972518
Can you elaborate
I've seen Wolf get a lot of hate on here but never known why

so why is there such a disparity between the 3d plot and the animation? is there any way to fix the 3d plot, because the animation is right, but i need the 3d plot

I don't know who the hell you think you are, Mr. Harvey. But I think we could change the world with these algorithms.

>>7971848
Sir, you need to find the short circuit current of your eel and how long it can sustain it.

When do the graph of sine and cosine cross each other?

>>7971755

I dont know. I can estimate it with graphs, but I dont know how to calculate it.

unless im just forgetting something really basic like an idiot...

>>7971740

[eqn]\sin \theta = \cos \theta[/eqn]
[eqn]\sin \theta = \sqrt{1-\sin^2\theta}[/eqn]
[eqn]2\sin^2 \theta = 1[/eqn]
[eqn]\sin \theta = \pm \frac{1}{\sqrt{2}}[/eqn]

Moral of the story, substitute either sin or cos and solve for the trig function.

only once we discover the power of triple integrals.

>>7971672
Yep.

>>7971672
Sure, why not?

>>7971565
in SR, write the product of m times v

then write v = v(t) since v depends on time t, then differentiate with respect to time t

usual the chain rule

then render manifest some acceleration a, which is defined as whatever makes you get the final result on your sheet

>>7971586
>then write v = v(t) since v depends on time t, then differentiate with respect to time t
What I posted is the entire text of the problem. There's no v or m given elsewhere to differentiate, or any other functions for that matter.

>>7971593
you are wrong

you know that F = d/dt (mv) which is true in SR

but in SR the mass m= m(v) is what is given, with v depending on time t, so you must be careful when you differentiate wrt the time t

in newton, mass is cst wrt the time t and the velocity v.

your whole problem is a chain rule.


guys am I the one with a fucked white css for 4cha now which happened 1 minute ago?

a pulsar is a mathematical entity.

nobody knows what a pulsar is outside math

"You will never"

there's more hydrogen in the universe than other elements. what else you fucking idiot? jesus how is this a question? think about it; the progenitors of other elements are these stars. when they exceed a certain size they reach a critical phase that prevents an accretion disk of a large enough scale that could produce fuckhuge exoplanets.

>>7971003
The rich get richer. The biggest object around tends to accumulate more mass than other nearby objects, making it even bigger, and even for likely to pick up mass, and so on. Also with the really big ones a lot of their volume isnt particularly dense

>>7971009

>there's more hydrogen in the universe than other elements

That doesn't tell me shit.

> what else you fucking idiot? jesus how is this a question?

Tell me how to price a European stock option. Speak with me in German. Write some code in C#. Getting the point dumbass?

>when they exceed a certain size they reach a critical phase that prevents an accretion disk of a large enough scale that could produce fuckhuge exoplanets.

What?

That's not a molecule. That's a sculpture.

That's not a post. It's a series of bits.

it's a bullshit molecule. it's missing some bonds. unless some nigger stole parts of it, the artist who made it is an idiot.
