It's Calc I with the partial differential operator to make it look scary.
Anyway, OCR for TeX is stupid easy, so if you decide to stroke your ego with everyone-who-doesn't-know-what-I-learned-this-past-week-is-a-brainlet and replace the Recaptcha with this, I'll just make a bot to spam this board with anti-vax blog posts until you realize your mistake

Considering these can be solved online easily, I suggest calc 1, but in simple word problems form. No spammer will know how to set up the calculations, in order to put them in solvers.

Also "I'm not a robot" should be "I'm not a brainlet".

>>8914027
/sci/ is currently /iq/ and /globalwarmingisfake/
No poster on this board worth their salt can't solve elementary integrals.

You are the ones that should leave this board, given that you are too stupid to realize that solving these captchas does not require any mathematical knowledge whatsoever.

Haha i know calculus im so smart xdd
Fuck off brainlet. This wouldnt solve anything

>>8914521
It requires you to understand how to input integral or derivative questions into wolfram correctly at a minimum, which most people don't know how to do without already knowing how to do them in the first place.

>>8914546
>what is symbolab

People seem to misinterpret the purpose of such a captch system.
It is not to make the people who can solve it feel smart, it is to make sure that the posters have a base level of knowledge and could contribute to the board.
I for one would support what this anon said >>8914310 so that solving the problem would not be a matter of using Wolfram.
I see no logical argument against such a system to ensure that each post has a bass level of understanding before being able to 'contribute' to the board.
This is a science board and the foundation of science is mathematics, having a test of mathematics before posting would be a worthwhile system.

>>8914001

>>8914589

I absolutely agree with this, and I admit I'd be very curious to see which threads would become more and less common and how the board's political and religious debates would change.

At least it might slow them down though, and if you're making really horrible b8 the effort of going to wolfram alpha might be too great.
There's really nothing negative about it.

You should know basic math if you are 18 years old or older.

>>8913970
That's high school math. It won't even prevent underage. It will only inflate their ego even more. Now people who post here will think they are mentally superior to others for knowing basic calculus. This is the dumbest idea I've seen on /sci/ this whole month.

>>8914956

Honestly just try it. There are very few disadvantages other than posting taking a bit longer, which isnt a big deal, and potentially is can improve the quality of the board.

Try it for a weekend and see how it goes.

You don't need to replace google recaptcha. You can add this as a second captcha.

Also, you dont' need to even use calculus. There's a shit load of math out there. Just an example in the OP doesn't mean you are only allowed to use that, brainlet.

>>8916745

I'd have to look up what the backward six in the far left was, but part of me thinks you could just simplify that to 1/X, I can't really remember. How do you graduate high school without knowing absolute value and trig?

multiple choice questions with a timer would be best tbqh. something that's quick and relatively easy to answer, but takes time to look up (and also stops >>8915221). something like: which of the following is false?
f is differentiable -> f is continuous
f is monotonic -> f is integrable
f is integrable -> f is differentiable

>>8913970
I think it's a good thing to implement. It'll cut down the shitposts. They can look it up but 1. too much effort and 2. underages won't know this stuff yet to look up. There's no reason NOT to implement it.

>>8917605
You can also ask for the names of important or famous theorems. Stuff like mean value theorem or Lagrange's theorem in group theory.

>>8913970
This is pretty nice, but only short ones. Otherwise it becomes a chore.

>>8914001
If you don't know how to differentiate a single variable function you don't belong here.

1. it's doubtful that 4chan can get anyone to pay them money to do this, the way they can make money from recaptcha

2. It makes it easier for bots to solve. Unless you're using random fonts or warping the image of the equation, a bot can read it and solve it easily

>>8917629
If it was something like "find the first derivative of y = 3x^2 + 2x" id be okay with it but come on now no one wants to do more than 10 seconds of math just to make a fucking stupid post

>>8917645
even that's too long. if it takes longer than it does to select 3 store fronts currently then it's not worth it.

maybe if you don't like shitposting, get the fuck off 4chan?

It also is easier for bots. You're saying you'd rather sift through "Jennifer Lawrence blowjob watch now!" shit 24/7 than the occasional /pol/baiting.

>>8917769
>It also is easier for bots.

It isn't when the math is written like >>8915835 unless you have some whiz bang strong AI bot. In which case just use it on google's current captcha system.

>>8917583
Probably not. You can bluff all you want. If this get implemented, you'd never been seen again on this board, brainlet. I bet this thread has you shaking in your boots, kid.

>>8917633

Just use "harder" math, brainlets. Although, most morons call calculus the hardest math they've every been subjected to. Personally, I think it needs to be several types. Like 3 problems to solve plus the google recaptcha and the type of math cycles among the 3 you ave to solve at any one time. You could slip in random stuff from various sciences. Like folding protein tertiary structure.

>>8918497
personally i think you should be given a randomly generated theorem that you would then have to prove and send to the /sci/ moderators who could then verify it and let you post.

I swear the people who post these threads just want to jerk themselves off. Assuming it was added, with the 'brainlets' gone, the bottom X% of the board will still be considered brainlets until another captcha is added, and this will repeat until only one poster remains.

Also what fucking retard wants to divide this board even further? Just block anybody from posting on /sci/ if they've posted on /pol/ or /x/ within an hour, it's clearly just them shitting the board up

its not about elitism. if youre studying maths or science and youre over 18, then you will be able to solve a basic calculus problem. if youre not over 18, you shouldnt be posting here? if you want to study maths or science, you can literally learn how to solve the captcha in a week.

That's just retarded. Any idiot can type the problem into their calculator or something retard friendly like wolframalpha and get an answer.

If you want to have a captcha that isn't harder for humans than it is for computers, the captcha should require you to construct a proof for a certain statement using specified axioms. Something that requires the ability to think intuitively and in a very human-like manner while still being very much a brainlet filter.

>Also, the captcha is supposed to filter out the bots. Bots are good at math. /sci/ would become 99% spam overnight.

Try reading the thread. You'd need to do the normal google recaptcha plus the math captcha and there'd be various types of math presented in a variety of forms. Bots also need to be able to actually read the math problem. A thing which is easily obfuscated from them.
