Yeah you are. You can’t use electricity without it.

TIL I'm an HTML developer because I'm surfing on the internet

[-] steakmeout@lemmy.world 19 points 1 year ago

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.

[-] Muffi@programming.dev 41 points 1 year ago

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.

You may have used them indirectly in the compression of your image

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

[-] slackassassin@sh.itjust.works 29 points 1 year ago

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 1 year ago

Do I like math? Yes

Do I understand a tiny bit of it? Absolutely not

Me, whose going to start studying EE: 😭

[-] Ozy@lemmy.world 15 points 1 year ago

HAHAHAHA GOOD LUCK! I'm in my final year of my EE study and I cannot wait to escape this mental asylum

[-] Omgarm@lemmy.world 17 points 1 year ago

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.

[-] RushingSquirrel@lemm.ee 21 points 1 year ago

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 WARNING]

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.

[-] dasgoat@lemmy.world 17 points 1 year ago

Oh I am sinning like a motherfucker

[-] pingveno@lemmy.ml 14 points 1 year ago

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

[-] Blue_Morpho@lemmy.world 13 points 1 year ago

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 1 year ago

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 1 year ago

TIL cats are really bad at math.

[-] prime_number_314159@lemmy.world 15 points 1 year ago

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.

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

[-] Honytawk@lemmy.zip 12 points 1 year ago

That is just cause you are unemployed.

Your phone relies on trigonometry.
