I found this in the solutions part of my textbook. Why does this even work? There's no explanation at all.
How is bringing up the derivative of cos here even relevant to finding this limit?

>>7857855
They recognized the limit as the derivative of cos(x) at x = 0. Pretty funny desu.
>>
>>7857855
because the limit is exactly, term by term, the derivative of cos at 0. that's nice
>>
>>7857872
But why would they write this shit like that? That's like writing that the limit equals 5^(0)-1. Illogical, and makes no sense at all, even though it's technically correct.

Is there an easy way to square this equation?
(ax^2+bx+c)? I always have to write it out and do it manually, is there a specific formula or something?

[eqn](ax^2+bx+c)^2 = a^2 x^4+2 a b x^3+2 a c x^2+b^2 x^2+2 b c x+c^2[/eqn]

Hey /sci/, can you guys come up with an algebraic expression that ends up equaling out to xy=qt3.14? Valentine's day is tomorrow and I think that'd be nice for the inside of a card. X & Y will be replaced with initials.

Sure anon!

1 = 3.14qt / xy

Hope this helps!

>>7857680
>>7857680
q(t) = cv(t)
the equation for the charge of the capacitor
if c= 1/(3.14)

q(t)*3.14 = v(t)
replace v(t) with X Y
she'll suck your dick straight away anon

There are some exercises in my calculus books that are limits of x approaching 0, with x < 0 being written under them.
How does one solve this kind of limits? Or at least, what terms should I be looking for on Google?

I'm 21. What's your point? I dropped out of high school, and want to get my diploma this year by studying alone.
Dipshit.

Anyway. what's the difference between left-hand limits, and x < 0 being written right under the x approaches 0 part of the limit?

2. What would happen if you "forcibly combine" them by let's say raising/lowering the temperature/pressure/...

So what does /sci/ believe happens from the observer's perspective when it dies?

There are no correct or incorrect answers. What do you personally believe happens? Let's have a good old fashioned speculation thread.

Bullshit. The correct answer is you die. Anything else is just made up nonsense.

OP's thread does not deserve propagation, because he was clearly just visiting the old meme-website ytmnd.com and lazily came up with the idea for this thread with same ideas and source material without mentioning the old website.

The below is something that OP was probably just looking at, and was a noted "xD random meme!" about ten years ago, involving cats and metaphysics. In fact, the web page was created well before the youtube "keyboard cat" meme took off, which OP's filename disingenuously references.

>>7856891
Blah, damn my kind terminology. Replace 'correct' and 'incorrect' with 'right' and 'wrong' if it helps oneself understand that this is for speculation.

>>7856903
>this dense, making an assumption and posting their own link. Nice try Mr. Viruspants

I'm still up if anyone wants to add value to the thread. But, it's looking quite lame... Thank goodness I still have myself to talk to.

Why does Methylated spirits cost more than white vinegar if it's also made out of ethanol but with one less chemical reaction?
14 posts and 1 images submitted.
>>
>>7856575
because things cost is based on what you can get away charging for them, not what they cost to produce.

vinegars food, nobody is going to spend a lot on basic food ingredient.

methylated spirits is a chemically sounding high tech liquid probably used by science or some shit. Its gonna be pricey
>>
Product prices are dependent on how much the consumer believes its worth. The only people who don't believe that is the consumer.
>>
>>7856594
>>7856609
If you buy acetic acid in bulk it will be as cheap as methylated spirits, so it's more of an economy of scale issue however you are right in that plebs should wise up and buy concentrated acetic acid and water it down to what they need because it's the same fucking thing but 1000x cheaper than store vinegar.

do people get degrees because muh jobs or because they're passionate about the field? and if it's the latter, are they better off in that field finding jobs than those who are just reeking desperation about making money and so forth?

i hear people telling me science and medicine are dead fields and that i should get a degree in walmaranomics becuase it's a more viable area and i'll get a job at any retail outlet i want.

Because they get a job. Most kids in school are in a degree because "I was always good at _____", "it pays good", "mom said so" or "idk, lol".

You are bred to perform on tests, to recite, memorize and repeat. You're not harbored into a learning environment to enjoy what you do. Most kids, and a majority of high performing kids do these specific tasks well. It is no true metric of their intelligence or skill, just a dick measuring tool parents use to convince themselves they did the right thing.

>>7856437
It's funny because you are bitter.

I can bet you anything that you don't even have a degree yet. Probably still an edgy freshman.

honestly why even get a degree? you're basically fucked.
