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.
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.
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.
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.
Or building some stairs or really a ton of shit. Basic trig is such a useful thing that it tells me people who complain about it have never built anything, virtual or physical.
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 other fields I get (trig is insanely useful), but how the bloody hell does one use trig functions in philosophy? Are we gonna be triangulating the border of science to solve the demarcation problem?
Fair enough, but did they use it? I always felt like focusing on statistics instead of random trig stuff for non stem people people would be more useful
Agreed, I use highschool level stats knowledge on a nearly daily basis, whereas the last time I did any trig was to follow along with a math video I was watching on YouTube. Trig/calc were mandatory, stats was not.
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.
There is hope for you after the asylum. My daughter has an EE degree. While in school, she would call me every October and tell me how terrible it was and that she wanted to drop out. I would talk her off the ledge, and she got through.
Now she's working, making more money than I do in her early twenties, and she loves loves loves her job.
Luckily I have 6 years of Electronics manufacturing experience, so the math and theory are the things I'll need to learn most of. Unfortunately, those things are the hardest part...
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.
The reason they drill it in to the extent that they do is so that you have a foundational understanding of the underlying math on which to build new knowledge. If you show up in calc 1 in college without remembering even the basic concepts you were previously taught in things like trig....that can really bite you in the ass. My teacher LOVED pulling out classic substitutions for Secant, Cosecant, and cotangent (No, i didnt outright remember them from Trig, but I had seen them, and that made refreshing much easier). Also these concepts then form the basis of many other fields such as physics (electricity/magnetism, kinetic motion, optics, etc.), chemistry (quantum, MO theory, and things relating to the physics side of why chemistry occurs), and many of the graphing concepts used in engineering/stem only make sense if you have the foundational understanding of what integration/derivation are. Those stem from understanding how to graph complex functions by hand (like we did in trig) so that when you are doing it later with assistance, you still GRASP what is going on.
Yes its not perfect, and yes for people who never need that later in life it can suck. However, I would make the argument it is better to have more of your population educated to a higher standard than what is needed in daily life, than to only give that to those who are aware enough at a young age to actively seek said education
A^2 + B^2 = C^2 is known as the Pythagorean theorem. This theorem explains the proportionality of the 3 sides of a right triangle (a triangle with 1 corner angle = 90 degrees). If you know the length of 2 sides (in his example, the wall beams) you can find out the length of the third (in his example, this would be the supporting strut spanning the beams that meet at a 90 degree angle). If their example is explaining a beam that spans the room from 1 corner to the other, you still use this formula as a rectangle is 2 right triangles that meet along their hypotenuse (the longest leg of a right triangle, or the length you are solving for in this problem). The 2 known sides are the length/width of the room, and you solve for the 3rd side, your diagonal beam
Building anything requires trigonometry, unless you just say "fuck it" and hope the thing doesn't fall apart, which is a pretty stupid way to live life.
Chicken coops have a ramp for the entrance, so when building it, you need to know the length of the ramp required for the desired angle, as well as making the"rungs" (I don't know what they are actually called) on said ramp flush with the ground.
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.
Ratios can be used in trig -- if it's 1.5 times as long as it is tall, tan(\theta) = \frac{2}{3}, which then allows you to find the lengths of the other two sides easily so long as you have a calculator.
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.
did you know that adding up all the divisors of 1209 and swapping the last two digits gives you a number that can be represented as the sum of two cubes in two different ways? or maybe not, I'm just a cat :3
Not me. I went years without until last week I realised I needed them for a script that points an object at a target in Maya. Turns out trig is really fucking universal.
I used to, but I don't often find the time these days. Trig for days. Especially given most game input is in (x,y) format from analog sticks or WASD. Gotta turn that into angles! (Not that you need much trig to turn WASD into angles.)
In HS trig class I asked the teacher what was the actual logic behind the tan function, and she said "well it's just programmed into your calculator" and I said I realized that but how did it work, she told me to go ask the AP calc teacher.
He's known for a different meme, but he's used in this one and manages to look like he's posing at gunpoint after being told "look casual and not afraid. Now, smile."
