One day it'll come up

This is dumb. Just because you don't use logarithms doesn't mean you never use deduction or process of elimination. Math is not solely about the numbers. The process is far more beneficial in many disciplines.

Also, the smart kids in class sure use them often enough.
The same vain is people arguing that schools should be teaching important things like budgeting, interest rates, taxes etc.
These things a trivial if you have the maths skills. These things are also subject to change, the maths doesn't.
Worst of all, these things are all taught (in Scotland), the people complaining about school not teaching them weren't paying attention.

I make games. I use this shit daily.

- We just prove a solution exists then get a physicist to actually do it for us.
- just use the complex exponential /j
You're also technically using them if you merely play games. Edit: You also use cos when making or viewing a jpg, so the author of the meme did in-fact use at least cos on that day.
I don't remember where, but I actually had to use some sin func for calculating something to play more efficient.

It's also a day without using anything he learned in art, or geography, or chemistry, or English literature, or history, or pretty much anything he studied in school after age 10. Why does math get singled out?

Because hurr durr math hard
Because math is abstract and difficult to relate to. We should be taught practical applications of the abstract concepts, and the exam questions should be more practical.
- I demand only the practical parts of art and history be taught in school.
  Also - the questions that focus on practical applications are called word problems, and they get complained about more than anything else.
- The biggest thing I learned from math was training yourself to think and problem solve. To always want to learn the next level of whatever you were learning, whether it's math English or whatever.
  I don't think I've ever used much math knowledge in my life ... but it gave me the ability and enthusiasm of wanting to always want to solve a problem no matter how complex it was.
- The reason why they're abstract and difficult to relate to is because we're all being taught maths backwards.
  In science, a phenomenon is observed and then maths is used to create a set of equations describe it's behaviour. Then using the equations, other experiments can be designed to prove other hypothesises. This is known as the experimentalist approach to science.
  Engineering is the same but less research and more application focused. For example, I need to design a wooden shelf that is A inches/meters long and supports B lb/kg of weight. How do I do that? Using trigonometry and Newtonian physics to work out the dimensions.
  Finance is often used for basic algebra and calculus.
  However, it is not always helpful to work in the material when using mathematics and the abstract is preferred. This is usually only useful for the theoretical approach in science, in theoretical mathematics, or at the cutting edge of engineering disciplines.
  If we were taught by being presented with a problem first, I think it would make it easier to make the leap into the abstract when required for other applications. And on top of this, it would make it much easier for the majority who only ever need to use mathematics as a tool.
I think it's because some types of math are kind of all or nothing, either you know it or you don't. If you recall half of what you learned in history you have some usable knowledge.
Another day of not needing to know that Constantinople was the capitol of the Byzantine Empire.
Of course these days they go by a different name. Not sure why tho
- They call it Istanbul, not Constantinople
I use basic math daily. I use algebra frequently.
I have not use trigonometry since I passed high school trigonometry.
Most people in modern society don't use it.
- 3d graphics and video games use a lot of trig
- have you ever played a video game where you're throwing a grenade and the UI shows you where the grenade will land?
  Just trying to think of the most basic uses of trig that would occur.

I literally, 30 seconds ago, used sin^-1() to calculate the angle for a roof I need to make for my indoor greenhouse, so the asshole cats don't fall through the cheap plastic

Always a good day when you have to break out arcsine

This is the weirdest ad for MATLAB I've seen today

Machinist, Drafter, all about that SOHCAHTOA Life 🔫🔫😎

Bro doesn't even use the internet, nor the electricity what a madlad

I use them all the time for game development

My dnd group has pulled it out a time or two when cliffs are involved to figure out if you could get line of sight on someone.
We're all engineers of some kind.
- Haha that's a great time, love having groups like that
I can't even remember what they're used for
- Trigonometry, they're used extensively in 3d programming

That man don't need no tan

I had a maths teacher who upon being asked, whats the point in maths? Or whenever he heard I'm not going to use this in the rest of my life! Would break into a ten minute speech. You have to study maths because what it is at it's core is just doing the same thing over and over again with slight variations. -more waffle I can't remember- and after school you will go off to some job where you do the same thing over and over again where you will spend the next 60 years of your life. And then you die.

It got quite depressing.

"No John, you probably won't ever have to use trigonometry in your life. But some of the smart kids probably will"
at it’s core is just doing the same thing over and over again with slight variations
Man, that just makes me hate how maths is taught

I use these functions literally everyday.

It’s like having a pocket knife. Once you start carrying sin/cos/tan around everything looks like a trigonometric relationship
What for?
- I am a machinist by trade. I have to know these functions in order to do machine setups, calculate points on a tangent radius, etc.

If you ever have to cut a bit of wood to act as a diagonal brace it's pretty useful to whip out the old tan. So I've used this every time I built a gate.

That's four times in the last decade, so not exactly daily but I'm glad I knew how to do it or my gates would have sucked.

I've got a table to build, and I'm doing my best to remember the maths needed to figure out the angles before I start cutting the wood.

If you use nothing from school then you’re going about life wrong. Reach higher.

I was trying to figure out a problem the other day and realized that if I still remembered how to implement some sort of mathematical concept I learned back in high school I would've been able to do it. Made me want to call up a friend and say something like "it finally happened!"

I think carpenters, framers, cabinet makers, etc use more math than I do day to day working as a devops engineer with an aerospace degree.

Cries in audio programmer.

I mean wasn’t soh cah toa written at that abandoned colony. Bad juju man

Im basically a mathematician and never use trigonometry, but I use a lot of probability and statistics every day at work.

:cries in arctan2:

What do you mean, cuz? You literally sin every day. 🤡

I prefer to cosin.
- No bro, that’s illegal in most states.

I use sin all the time.

I always yearned to understand a practical reason to learn calculus. My teacher at college was a German woman that spoke English with a thick accent. Her joy for the course seemed self-evident, but she failed to ever share a real-world reason or application for what we were trying to learn. 45 years later,I still haven’t used what I “learned”, or ever came to understand why we did.

I always yearned to understand a practical reason to learn calculus.
I use my understanding of second and third derivatives and the risks and how they affect the likelihood of black swan events - to choose (strongly influence) who loses when playing a game of "Liars Dice". So there is that, I guess.
On a more serious note, lots of things in personal finance are a bit easier to understand with a functional understanding of derivatives and integrals. It's not critical, but it makes stuff like the compounding time effect of interest more accessible, I think.
Edit: If I could change one thing about pubic schools, I think everyone should get a chance to take stats or probability for free. It helps so much with so many areas of life.
Calculus is how I think about physics, and specifically used in almost every way I physically interact with the world. When thinking about whether to accelerate to pass someone, be it walking or driving, that's calculus.
It's the highest level of that math that comes intuitively to me, and I suspect that's why I think in it. I suspect smarter people than me go through life intuitively thinking of everything in higher forms of math.

y'all seriously don't SOHCAHTOA everyday?

If you listened to music, your phone used them about a billion times. ... well, not exactly since more efficient algorithms than full perfect computation exist, but...

Same for GPS, cell signal processing, camera functions... They're all over the place. Taking that picture required it.

While it is necessary to understand the background, digitized sampling and Fourier transforms of the data don't calculate sin/cos/tan.
- Like I said: more efficient algorithms have been figured out. That doesn't mean those equations are magically meaningless or not involved conceptually. Trigonometry is everywhere, doing important things.
