Basic trigonometry is super useful and not that hard to understand or memorize.
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.
Same but "you're in middle school, that's high school stuff"
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.
It's a valid complaint. Why is Shakespeare more legitimate than, say, Stephen King for high school classes? Reading is reading, and asking students to read boring books because "they are classics" is the best way to discourage them.
In high school, I had to read Phèdre, a story told in verses about some incestuous rednecks from Greek mythology or whatever, written in the 1600's. It was painful.
For that matter, why do we read Shakespeare? They're plays. Watch them as plays or movies. If kids first exposure to Star Wars was by reading the script, they'd hate that, too, and they should.
I had to read Shakespeare, then read another book about how witty and clever it was to the people of the time, then write a report about how witty and clever it was, once I understood the historical context. My conclusion that having to explain jokes is the death of humor got me a C-.
There are a lot more authors who took inspiration from shakespeare than Steven King. Shakespeare is just objectively more influential, tropes he invented are used all the time in many places and there is value to understanding where the source comes from.
I think there's something to be said about shared cultural experiences, and so reading some older books is probably a good thing.
To clarify what I mean though: that means that we should be reading stuff that was written/popular when our grandparents were our age. Going back 200+ years should be saved for a history class cause that's the real value in reading that material. In my opinion, Great Gatsby should be about the oldest book kids need to be reading for a literature class these days, and even that's pushing it.
It's the exposure that undermines it. Their isn't enough exposure to real life application and examples. How many people never realise that velocity is a derivative of position over time or acceleration is a derivative of velocity over time. Or that the speed of light is a horizontal asymptote for matter.
Ah yes, because plumbers, electricians, and brick layers never have to deal with geometry. That being said, none of my geometry education was taught with a practical motivation. But that being said, I was in the advanced track classes, so none of us were becoming professional carpenters. I'm actually probably one of the most "hands-on" people from that class, both in my job and in my life. I build scientific instruments and enjoy fixing things around the house.
