Seriously, is this achievable?

I'm sure traffic onto /sci/ would reduce by 90%, but seriously who gives a fuck when this board is already shit. This board would be super comfy if we got rid of all the /pol/ and SJW lurkers.

>inb4 too hard
no it's not.

fucker you know what I mean; what you want people to prove the Cauchy-Schwartz Inequality in a captcha? shut the fuck up.

Solvable by computer doesn’t work. You’d need this with a captcha

Link to captcha program that parses TeX and evaluates arbitrary mathematical expressions?

how would you even go about getting this implemented?
I'm not asking on the technical side of it (how you'd program it), but rather, how you would get someone to implement this on 4chan? Who would you even contact, and would they even agree to it?

Do you really believe the average /pol/ poster has the capability to type pic related into Wolfram?

I have no idea, if I did know I'd maybe put in ten minutes a day to try to get captchas like pic related put into /sci/ permanently.

I guess the best place to start would be to suggest it under "Feature suggestion" in the 4chan feedback form: 4channel org/feedback

Just use something like sympy and generate some equation with random settings out of templates parse it and check the answer. To prevent computers from solving the captcha by using OCR just insert some noise or do some other things. Shouldn't take you more than a day to implement it.

If they're smart enough to write the parsing code, they're smart enough to post here anyway.

Captcha images are hard for computers to parse.

A nice equation like that would be pretty easy. Someone could write a plugin that auto-completes these.

Pointless idea

It's not like being good at calculus implies someone is reasonable, sane, and a good contributor to a discussion

then again I guess it can't do it all the time
The input was "\frac{\partial}{\partial x}[7\sin(7x-\frac{\pi}{2})+\cos(3x)]|_{x=\pi}"
I might just be bad at latex though

You should just ask if they clamp. Anyone who says no is divorced from reality, and shall be barred from entry.

btw that pic is fucking retarded since it uses the symbol for a partial derivative even though it is a single variable function. OP is a moron.

What would happen if you took a "prove you are human" and combined it with a "prove you are NOT a human" type captcha... What or who would be left? What type of website would need something like this, and who/why/what are they catering to?

Could we make such a captcha for a website? Just to see who would show up?
What if we made a brand new chan and each board had a board relevant captcha, In fact each board could be defined by the type of captcha challenge (which is kinda what OP wants) (e.g. /v/ would be video game trivia or possibly an actual mini-game with a 10 second platformer challenge, /g/ would be simple program challenges, math/science is obvious) but the true purpose of this new chan is to hide this new honeypot of a captcha that filters both human and bots. Who's going to be posting on this new board? I'm too scared to find out.
