2x = (90 +360k)
x = 45 + 180k

^but this isn't always correct either, how do i distinguish when k is nondivisible by 2?

>>8007940
it's a bit tricky since your original equation was basically for x from 0 to 360, but when you take 2x= sin^{-1}(1) you only get answers for 2x between 0 and 360 even though the number you want is more than that. i.e.
2x=sin^{-1}(1) implies 2x=90 OR 2x=450
and so x= 45 or x=225 but only the second one satisfies the equation you started with

>>8007951
when you square an equality you have done a non-reversible step which can add additional solutions, since a^2=b^2 does not imply a=b. so you always have to make sure when you do non-reversible steps that your final solutions after work with what you started with

I shitpost on 4chan and play video games with internet friends.

I won't toss myself at poetry
Mainly cause I'm drunk
So there, I went to my mate's
And got lit

Bump because I can't be the only one without a life
I spent all night long
Learning calculus two, too.
God, I want a life.

This is not correct

Source on info about Feynman's IQ?

I have (supposedly) IQ of 156, but I never pursued career in /sci/ related areas.Such a shame.

Elon Musk is too proud to be successful in the long run. I'm almost certain he only keeps going on by stealing other people's ideas.

>Since nihilism is the cumulative consequence of a rational/scientific approach of life
not really correct though is it? it's still a very grey area but pop-sciencey types like to make it out as if the big questions have all been resolved.

If people were more honest they'd admit that they just don't know but the current fetish is to act out the super rational atheist/nihilist a la dawkins.

if this is bait you could at least make an effort.

>>8006514
I see your point, but the idea that life is meaningless isn't as farfetched as you make it out to be.

Just take the scale of terrestrial life compared to the size of the universe, only that makes all terrestrial life negligible. Working with the most probable outcome inevitably leads us to nihilism

>>8006505
If you get joy out of finding stuff out, then why not do it?

you already made a thread with hillary posting here buttboy : >>8005717

If you're going to say it begins at conception, you might as well say it begins when sperm is manufactured.

>>8005767
Well, it's pretty complicated and depends on what definition of life you use. I say that a human fetus is both alive and a seperate entity when it can survive outside of the mother's body without the mother (technology is fine, I just mean living without being in the mother's uterus). So, this isn't a great definition because that definition will change a technology progresses. Another good definition is the existence of the brain. Of course even that definition is somewhat complicated, but I use the definition of a basic human neurostystem. This has not formed by week 7 or 8, so I feel very confident saying that abortions that happen by this time are not murder (65-67% per http://www.abort73.com/abortion_facts/us_abortion_statistics/).

Any biologists here?

How do we eradicate the gay gene ?

>>8005737
Biology gradfag here. I'll try to do this justice, although I'm more of a bench scientist than a theoretician. Although this is certainly interesting, there are more parsimonious explanations biochemically and genetically for complex behavioral traits such as homosexuality.

Chimerism is presumably the result of a random process, although recent research has found several loci and related alleles that seem to predispose carrier females to have twins at a higher rate. There may be something analogous with chimerism that we haven't found. Evolution works slowly on biological systems that are excessively noisy (random) or dependent on nonlinear interactions. Chimerism is by definition a highly stochastic process and is likely limitedly evolvable at any meaningful rate. Also, true chimerism likely occurs at a much lower base rate than homosexuality. If you want to argue the role of microchimerism, that may be a different matter.

All in all, epigenetic effects such as histone modification are theoretically more likely and experimentally better supported biological correlates of homosexuality. Epigenetic programming is limitedly heritable, if at all, while still affecting an organism's development in utero and beyond.

While epigenetic processes may themselves be under evolutionary selection, the traits shaped by epigenetic processes are not directly heritable in their entirety, as epigenetics implies the physiological processes resulting from exposure to one's environment. This is likely a better explanation of why homosexuality has not been subject to negative selection.

I read this place as pure schadenfreude. The posts, posters, trolls, and futurists are denser than the core of the black hole shitposts that clog the board. I literally cycle between this one and /r9k/ just to reassure myself every night that coalesced retardation exists and that I know its location.

>>8005658
oh come on, they are not that bad.
Most of them are pretty smart, just trolling around.

>>8005678
Let's take a critical tour of the /sci/ catalog as of the beginning of this post, shall we?

>AI replacing all jobs in 10 years
trolling thread, not particularly inspired

>Redpill me on GM crops
shitty baseline pandering troll thread

>This topic
where I'm shitposting the entire board at once

>Simplified highschool physics backpatting thread
no one cares asshole, otherwise we'd all major in calculating parabolas for throwing rocks

>Questioning the moon landing topic
troll topic, though small chance that it attracted a retard thinly veiling fuel for a moon landing denial post on a different board

>Time travel thread
horseshit popsci garbage

>Gay gene discussion
shitty strawman for an argument that topic's OP isn't qualified to discuss, also trolling (badly)

>Bigelow thread
Fine.

>Why can't aliens be dumb instead of smart?
It's a longer OP, and the reasoning is superficial, banal, and surface-level

>What are dreams?
A long list of things that you could google if you bothered to.

>Stupid Question Thread
The eponymous thread.

>Making fun of their old highschool prof
Move on idiot. Also shitposting.

>Why haven't we cured cancer yet?
Bait thread.

>I don't understand the calculations behind the diameter of the universe.
Which is the stage where you re-read until you understand or have a more specific question instead of shitposting on a board where you won't get a reasonably summarized answer.

>What calculator app should I buy
Fine. Probably a good scope for the question.

>Redpill me
Trollbait

>Calculus is not advanced mathematics
Trash bait. Odd that some legit discussion of even basic problems happened here.

>Is my textbook a meme
Your shitposting certainly is.

>Sun of ice Sun of Lava
old

>mars colony
popsci futurist nonsense

>online color ""test""
first incidence of this to come up so far, but people linking vomit-ridden online tests is more common here than other boards.

I could go on.

>>8005368
Oh also, this is more in line with /lit/, but I'd also like to work on improving my vocabulary.

I should probably have posted this in /adv/, but the things I'm looking on improving and learning on are mostly /sci/ related things so I figured it'd best be a topic for this board.

What I don't understand is why this is big news now...http://www.deepspace.ucsb.edu/projects/directed-energy-interstellar-precursors

The idea has been around, and there are more implications to be made past sending a microchip to another star, but I guess everyone gets all hot and bothered when the nugget in the wheelchair says anything.

>>8004482

Well it's mostly because they also have the money to do it

>>8004030
Obviously not. It's a Chinese conspiracy to hurt the heart of the motherland America's industry.

Of course not, the world is flat and so is its temperature.

energy runs the world, the fact that we're on the cusp of being able to get it for less than we have been has made a lot of people nervous

the saudis are silently finding isis as a land grab in response to this
the sooner we stop dealing with these people the better

china know exactly what they are doing
