Let C (x) : Surface area of a revolution volume
And l (x) the arc length of a function f (x)

The first formula explains itself. I WOULD LOVE to know how to simplify it.

The second one was a thing i got when I was trying to find out the formula. MY Queation is how do i operate with it?

THE third one is the formula the book gave to me. How do I find out this formula?

You could simplify C(x) by expressing cosine using the tangent (Use identities tan=sin/cos and sin^2+cos^2=1).

You'll get something like sqrt(1/tan arctan(dx/dy)) and the trig funcs will disappear.

bumping for this.
i need to know as well.

Read the sticky and/or wiki.

Are the you middle school brainlet who switched from finance to physics? Give it up. You will fail.

what???

Hi /sci/. I usually browse /h/ or /hm/, but I thought you goys would be interested in this.

My mommy's a overpaid babysitter, and she sent me a math problem that she couldn't figure out herself. I confirmed that it was really tough, and this email conversation was forwarded to me. The test question writer insists that he is a HUGE autist.

This is exactly a rare occurrence too. I think the test question writers are sick of fucking with me via my mommy as a proxy.

>fixed

>>8727076
But OP hasn't asked for any help. So your response is unjustified. This is a thread where we collectively roll eyes at dumbasses. Initially, it was the author of the math problem, but now it is you as well.

What does it matter? Immortality should be first, cancer second, then everything else. It's not like we'll get to make a socialist automation-based utopia in our lifetimes anyway.

>>8727052
You do understand AGI, if friendly, will give us immortality and cure all ailments? Much faster than we'd get them without AGI.

"It" reads the shitposts on this website and determines the course of humanity through the power of meme magic. We are all directly contributing towards the creation of true AI. Not just AGI.

Lack of practice.

If you can't do it you don't understand it enough. This is not humanities where you can just read a text and understand it.
That's a deduction that a 146 IQ person could easily devise alone.

...why?

He's a billionaire. He could get AIDS and still have the body of the Terminator if he wanted.

*hierarchical

It serves no purpose whatsoever.

idk check your intelligence quotient maybe?

>>8726417
Your math working memory increases and your pattern recognition for solving problems related to math increases as well. Then, I guess there are applications of linear algebra to programming.

>>8726417
I see a lot of permutation groups in babbys first AI

A would be programmer would be better off learning hindi

And thus, how does gravity work?

>>8726241
how can electromagnetic space move through empty space, even though waves need a transmission medium? That's about the same question...
Space doesn't obey the intuitive rules you expect from matter. It's a whole different thing.

In what space does the space bend

Telepathy has been extensively studied repeatedly with a lot of time and funding, and yet there is still no proof that it exists. Very few things have gotten as many chances to be validated, but it has failed time and again.

The main problem with believing in telepathy is that it's testable, and it has been tested, and it has failed those tests. Telepathy is not real.

>>8726146
And the case?

It was made up by fake news papers to sell issues. Do you think Bat Boy is real too?

But why does it feel like there is? Assuming my brain is just chemical reactions, couldn't I do everything I'm doing now without being conscious?

>near impossible to prove

There is no such thing as "near impossible". Things either are impossible or possible. Same goes for other brainlet phrases like "almost infinite".

>>8726116
what do you think about the phrase ``almost all''

Common folk aren't trained to be thinkers. They're trained to be blissfully unaware happy go lucky slaves. Be happy you were born in a wealthy family or were afforded the privilege to experience the joys of intellectual pursuit.

>>8725627
You go to a place where actually intelligent people are, or you talk with someone who's vastly smarter than you and crushes you like the bug you are

>>8725640
>trained to be
Can we let this stupid meme die? The majority of people are never going to be leaders or thinkers. You can't train someone to br curious and creative.

>>8725593
It's just one person with a lot of time on his hands.

but I suppose you know that, don't you?
