How many of you could continue to post on Jow Forums if the recaptcha was replaced by a math captcha?

t. mathlet

x = 1.5708 - 5.12393i + 2πn with n in Z
x = π - 1.5708 + 5.12393i + 2πn with n in Z

why would you use a captcha that can be easily solved by robots but not humans????????????????????????

Is there a linux program to solve equations like this? Could be pretty useful.

Mathematica itself, SageMath, Matlab.

exactly, the solution isn't real, making the problem impossible

this would be so easy to break with a bot desu

Any scientific software works on linux, if not primarily.

Mathematica (for symbolic calculations it's the absolute best)
Matlab
Maple
Maxima
Sage
Sympy
...Octave

>exactly, the solution isn't real, making the problem impossible
t. I am still in HS and don't use complex numbers on a daily basis

You can cancel an x out of the top and bottom, leaving it as sin(x)/2, which covers the range [-1/2, 1/2].
Maybe there's a solution with imaginary numbers, but at that point you've already filtered out the vast majority of humans, and a relatively low amount of bots.

Just write it as a "precise" solution. :^)
x = arcsin(84)

it is true you could make use of euler's formula to derive a solution, but we're assuming that they want a real solution. and if you're going to call me out as being a mathlet, at least leave an exact answer

x = π/2 ± i ln(84 + sqrt(84^2 - 1)) + 2πk k є Z

guess i'm fukt m8

>he added a nonreal component
does your girlfriend know you spend time thinking about this shit?

let's be serious; the vast majority of Jow Forums probably couldn't solve a basic system of equations, let alone this

84?
I cant remember. Doesnt sin(x)/x equal 1 for small value of x.

I'm a physics major. So yes.

Who gives a fuck about math anymore? I'd write a C program to do it for me

what was the name of that browser add on that solves captcha again?

This would be a great feature for this board. Should use discrete math instead though.

I'd be fine

If I wanted to learn mathematical syntax I wouldn't have become a computer programmer in the first place.

Likewise for solving math problems with my mind instead of a COMPUTER.

see

I saw it. What effect is it intended to have on me.

Can't solve with a computer :^)

Is this a practical thing or a masturbatory aid?

could and would are two different things

>assuming
Don't

Lebesgue integration is used to define the basis of QM and Fourier analysis for example and anywhere else that depends on measure theory, but it's more of a formal tool used for that, and not often used for calculation, so more in the formal side.
However it is more powerful than traditional riemann integration and hence can be used to calculate integrals of more wacky functions.

?
42(2x)->84x=sin(x)x
divide by x
84=sin(x)
sin^-1(84) = x

Wow faggot. You took calc 3 ayear after I did

Is the answer 1?
Brainlet trying to do this in my head here.

Photomath

Yes, it would be 1.
In the space of [0, 1] (or any range on R for that matter), there are countably infinite rational numbers, but uncountably infinite irrational numbers. Therefore, the fact that f is 0 at a few points basically becomes irrelevant.

It wouldn't be close to 1, it would actually be 1, because if you were to integrate from 0 to 1 on a function that is 1 everywhere except it's 0 on one specific value in that range, the integral would still be 1. This is the same thing, but extrapolated.

No problem for me.

Linux is a kernel, it can't run software on its own

Math isn't that hard, this is what I'd be afraid of

Anyone have the install gentoo captcha?

>system that prevents computers from posting is implemented using something computers are good at
It would never work mate

>how to exit vim

arcsin84, ez

The only correct answer.

Do you have highschool education?

>linux screenshot
>how to exit vim
mathlet and linuxlet... no, lifelet.

Isn't the answer just 0?

This is easy though
I remember they used this on Russian lurkmore to prevent dumb zoomers from editing, caused a lot of butthurt. Would definitely benefit the Internet and tech communities as a whole though

-i*ln(84i+√(1-84^2)) ≅ -i*ln(168i) = -i*ln(168) - i*ln(i) ≅ -5.12396i -i*(iπ/2) ≅ 1.570796... - 5.12396...i
sin(1.570796 - 5.12396i)/2 = 42.0013... - 0.0000137248...i

this would unironically work really well because:
1) normalfags can't into flash
2) normalfags wouldn't browse in public if captcha was replaced by hentai games

>Complete the survey to continue posting

Well, I have a pass.

>Kernel can't run software on its own
Fucking brainlet. Tell me then how it starts init process. Linux can totally run without GNU bloat and it often does on embedded systems.

>how to spot a student website

>divide by x
nice move faggot
you must be a mathematician.

asin(84) into Wolfram Alpha = ~1.57

t. wolfram alpha

Moot should have added a kanji captcha to the weeb boards while he still had the chance

>divide by x
t. doesn't remember any math past 5th grade

I literally never learned this.

would just use a calculator and bots could easily pass it too

x=0 clearly isn't a solution so it's fine to divide by it

Thanks user, i am not familiar with this stuff at all. I still use bc -l for everything

Also, the best you can get for your phone IMO is Mathstudio from pomegranate if you're on iOS, but they also have a version for android - Mathstudio Express, which is also the best you can get for android, but it is missing some features from the main one, but I don't remember how much.

pomegranateapps.com/mathstudioexpress/
Though I don't know what happened to it as I can't find it on the google store anymore, so you'd have to get the apk.

An alternative that I haven't tested is Smath studio, which is a port of Smath studio which also works on linux and other desktop OSes, it seems to be really good, but I've never used so I don't know it's capabilities compared to the other math software, but it should be just as good. Which means the android version should at least be comparable to mathstudio.

This.
>Computer can do as level maths in less time then it takes us to blink but can't tell what a traffic light is

>Implying you couldn't just google / wolframalpha that

you could make it reload on tab change like google stops the slow fading captcha if you change tab. there are many ways to make that harder if someone wants to

hey we used to solve rapidshit captchas. we can do anything.

Inb4 they can now tell what a traffic light is in less than a blink of the eye because we have been training their self driving car ai with this shit for so many months now.

seems like that would be a lot better at filtering out humans than bots

>Divide by x.
Absolute state of burgermath

They have been able to do that since before the nucaptcha actually.

A computer could solve this quicker than a human could.

Yes, I'm a mathfag.

but it's something people actually use right?

Probability Theory

Not him, but yes. Some dude called olivier lichtarge has been using that in biology to formalize a theory of genotype->fitness mapping, for example.

Fellow physics Chad here to dab in these compsci brainlets.

Absolute retards.
