Why do you brainlets not even know how to ask stupid questions? At least post theorems 95 and 96, brainlet

>>9103701
Theorem 95. If the functor [math] F: \mathbf{C} \to \mathbf{D}[/math] creates limits of shape [math] \mathsf{J} [/math], it reflects them.

Theorem 96. Suppose [math] F: \mathbf{C} \to \mathbf{D}[/math] is a functor, that [math]\mathbf{D}[/math] has limits of shape [math]\mathsf{J}[/math] and [math]F[/math] creates such limits. Then [math]\mathbf{C}[/math] has limits of shape [math]\mathsf{J}[/math] anf [math]F[/math] preserves them.

Huh, while writing this I think I got it and I can't believe I missed it before.
Creation implies reflection and preservation, I guess.

Cant lie, community college is great for degenerates and sub-populations.

Sorry senpai, I JUSTed myself pretty hard in high school and I want to transfer somewhere nice.

The CC I used to go to was filled with brainlets (students and profs) and the CC my gf currently goes to is a factory for radfems. I'm not totally against CCs, but it's really hard to find any decent ones

You have three options
1) Get a free ride either because of previous academic achievement of because you are a minority
2) Kill yourself and pray that in your next life you are born rich and/or a minority
3) Suck it up and get loans but go to the cheapest university you can find (public obviously) and then through merit try to reach the stars.

be a mechanical engineer or electrical engineer

oh you said other than plumber or electrician
try physics dude there's a HUGE market for string theory

Practice more. There's no math gene, people only get good by practising. Leave /sci/ right now, read about the things you don't fully understand, and then practice every relevant exercise you can get your hands on.
If you actually do this you'll do really well, but you're probably too lazy to bother, and you'd would rather cry on /sci/ about being a brainlet.

>>9131409
this

just do practice problems.

Consider that (a+b)^2 = a^2 + 2ab + b^2.

So if you have a quadratic expression in the form x^2 + 2bx + b^2, you know how to factor it easily. Now imagine you have a quadratic in the form x^2 + 2bx + c = 0. How can you get it into your factorable form? Simply subtract c from both sides, then add b^2 to both sides. That is, take half of the coefficient of x, square it, and add to both sides. Then you have (x+b)^2 = -c + b^2, so x + b = +- sqrt(b^2 - c).

>>9130868
Also, if the coefficient of x^2 isn't 1, then just divide through by that coefficient first.

ax^2+bx+c=0
x^2+(b/a)x=-(c/a)
x^2+(b/a)x+(b/2a)^2=(b/2a)^2-(c/a)
(x+(b/2a))^2=(b/2a)^2-(c/a)

Now you can find the zeros by taking the square root of both sides.

The ring is temporary though, see it while it's still there.

If there's a conspiracy behind Saturn around this. I'll back it. I don't trust Saturn.

Saturn has a core, but it's not solid.
It is real
Saturn has no brain, it can't think
It has no purpose, it just exists.
These are all retarded questions, suck a fat one

>visualize images
But images are already visual, no? They shouldn't require any specific effort to be visualized. In order to visualize visual stuff, you effectively should have no graphic memory. Strange how you can type if you don't know what letters look like.

>>9130382
This would explain why retards can't grasp basic geometry or linear algebra.

>>9130397
It means that you know how they are but cannot visualize them in your head, only when you are seeing them atm.

For example, I have a lot of trouble to explain a course from A to B that I already know from my memories, but when I'm going from A to B, when I arrive at intersection or things, I know where I have to go.

I read somewhere that this, maybe, was a problem from some specific neurons that retain the images, but don't allow to visualize them, like a connection problem.
