The meme said they didn’t use it not that they didn’t apply it.

Nah, I hired an electrician to handle all that for me. Now if I want electricity all I have to do is stick a plug in a socket, or flip a switch. It's way more convenient.

Basic trigonometry is super useful and not that hard to understand or memorize.

[–] DeathsEmbrace@lemmy.ml 15 points 11 months ago (2 children)

It's because trigonometry is used to teach people geometry and nothing in real life application. You want basic trigonometry in real life we should use physics as a basis for why trigonometry is useful in real life. You can't expect theory to be used in practicality when nobody has any experience.

I don't understand, out of all of the things that we teach students in schools, out of all of the things that people don't demand justification for learning, why Maths gets all of the flak. It's the foundation on which the universe exists. If people don't understand that they're not just learning trigonometry "just cuz" then they probably don't have much of a career in STEM planned for themselves. Which is fine, but western society's blindspot for STEM is 100% attributed to the intentional undermining and dumbing-down of the education system.

We regularly don't give students justification for why they learn grammar, biology, chemistry, physics, visual art, and music. But as soon as you show someone a standard polynomial, they lose their fucking minds.

For me, my "education" with math was "when you see this: 5/73¥π7^t then you use 5-8(25&6)_9gh8/6 not 5&6(9!4_89) ok memorize it for the test.

Oh you want to know why or what it does or what it even is? No that's college work. You're in highschool, memorize it because reasons.

Yeah... That's not how my brain works no matter how badly I wish I did. I need to UNDERSTAND not memorize! I can't memorize seemingly arbitrary bullshit that has no explained meaning. My brain instantly tosses it as irrelevant information.

I dunno, I see people complain about "why do we have to read books that are hundreds of years old?" too pretty frequently. Some people are just hostile to education. Honestly, cost aside, I'm a little disappointed in the number of people who complain about college as if the only thing you get out of college is a piece of paper.

Trig is honestly the math I've used the most since finishing school. But to be fair, that is mostly because it's useful as hell when doing game development as a hobby.

if you were a more interesting person you could make up a use for them

[–] slackassassin@sh.itjust.works 29 points 11 months ago (7 children)

Best take right here. Trig shows up a lot when you actually do stuff. Woodworking, programming, physics, art, music, philosophy. Math shit is universal human language.

The only function is sine, the rest are just remixes and ratios

I like math :) Its mysterious and fascinating and constantly surprising, like seeing the source code of the universe. Closest shit we have to actual magic.

[–] PeWu@lemmy.ml 13 points 11 months ago

Do I like math? Yes

Do I understand a tiny bit of it? Absolutely not

Me, whose going to start studying EE: 😭

Electrical Engineers are the psychos for using j instead of i. Absolutely bonkers.

I use it all the time. I'm an engineer though so it doesn't really counteract what you're saying.

One day, while working on a website, I was wondering how to calculate a specific point in a graph. After googling, the answer was by using sine and cosine. Mind blew away, I had always thought I'd never use them.

Trigonometry is extremely useful when constructing things. Need to know the length of wood needed to go from corner to corner. That's trig my friend.

When you're in school you think calculus is the fucking shit, but in the real world you actually use trig way more often.

[–] pingveno@lemmy.ml 14 points 11 months ago

Meanwhile, pretty much every object in the room that had to be manufactured with any precision uses trig.

[–] Adalast@lemmy.world 13 points 11 months ago

Weird, I use them almost every day doing procedural animation and modeling.

[–] Blue_Morpho@lemmy.world 13 points 11 months ago (3 children)

I use trig every few years when buying a tv. Tv specs always list diagonal but rarely horizontal and vertical which is needed for knowing how a TV will fit in a space.

[–] lolcatnip@reddthat.com 13 points 11 months ago (5 children)

I'm trying to figure out how you need trig for that. Just the Pythagorean theorem and ratios seem sufficient to me.

did you know 1209 is a prime number? or maybe not, I'm just a cat :3

[–] Rakonat@lemmy.world 16 points 11 months ago (1 children)

TIL cats are really bad at math.

[–] prime_number_314159@lemmy.world 15 points 11 months ago (1 children)

1209 is 3 times 13 times 31, and cats are better at typing than they are at math.

In base 10, the sum of the digits of any number that is divisible by 3 is also divisible by 3, so 1+2+0+9=12, implies 1209 is divisible by 3.

Likewise, 1001 is divisible by 13, so if you split a number in base 10 every 3 digits, and subtract/add alternating sets of numbers, if the result is divisible by 13, the original number is, too. 209-1 is 208, which is obviously divisible by 13, so 1209 is, too.

Divisibility by 31 in base 10 is harder to check, but 999998 is divisible by 31, as is 999999999999999, so you can just split the number every 15 digits, and add those together, and if the sum is divisible by 31... I'm talking about math to a cat.
