Joke’s on you, I sin every day.

The smarter kids in your class probably do use them.
As one of the resident smart kids who went into CompSci and now works as a software engineer, I haven’t touched any of this for a hot minute. I mainly use it for 3D print designs once in a blue moon.
Of course it depends, but for example, it CSS esing functions are based on polinomial or sin waves. If you ever want to understand or perhaps implement and easing function, trigonometry has your back.
Nah. I was labeled a dumb kid in high school because I had to work 40 hours a week. I went back to college as an adult and now have a masters in mech Eng.
Went to my high school reunion and the smart kids were largely abject failures. They never really struggled until college, then mostly failed out. I felt bad for them, but not too bad since most of them bullied me.
Sounds like maybe there weren’t the true smart kids. You finished high-school while working a full time job. You were capable and adaptable. Fuck them :)
Thank you for that.
But you use things that use them.
like any device that uses graphics
There is at least one smbc for everything
Never really understood people who say they don’t use algebra. I use it very regularly.
I was thinking this myself. sin, cos, tan. Have not used. I have use euler coordinates so thats something but really solve for x is the most advanced thing I have used outside of school. mmmm actually I guess some statistics like stadard deviation.
I recently had to do a two variable equation because I was using a recipe that called for a specific milk fat percentage by mixing cream and milk, and my cream was heavier than what it needed. That was really stretching the limits of what math I remember.
Programmer for 25 years. Only time I have ever used math more complicated than simple multiply/divide was… actually never.
That one time when I copy/pasted a formula for linear interpolation, was still just multiplication and division. And I still have no idea how it works.
I’ve even done OpenGL and graphics programming and still haven’t needed any algebra/trig/etc, although I don’t do complex 3D rendering or physics or anything like that.
I wish I knew how to do cool programming stuff like draw circles and waves and stuff though, but I’ve never seen a tutorial that didn’t go WAY over my head immediately.
Drawing a circle is actually pretty simple! Say we want to draw one with:
- radius r=5
- center C=(0,0)
- 1000 points
The logic would be:
for (let i = 0; i < 1000; i++) { // full circle is made up of 2 * PI angles -> calculate current loop angle const angle = (2 * Math.PI) * (i / 1000) const x = r * Math.cos(angle) const y = r * Math.sin(angle) drawPixel(x, y) }The circle starts being drawn at (5, 0). As y approaches -5, x gets smaller until it hits 0. Then x approaches -5 and y approaches 0, and so on.
That won’t work well ;-) it will draw 1000 pixels whatever the circumference!
A good start though, for sure.
It’s just meant to be a simple example. If someone says other tutorials quickly go over their head, it’s not a good idea to introduce unnecessary concepts to start with.
I use them every day. Making science is rad as fuck.
As opposed to degree as fuck.
Almost made me do a π
I see what you did there.
Sin, Cos and Tan were gifted to us by the gods, and it’s solely your fault, if you don’t use them daily in your freetime.
Know any good resources for math-ignorant programmers that teaches how to use those in useful ways?
I use them at least once a week
Every day, I use them ever damn day.
For determining the right angle to fuck the sharks from?
I love whipping out the low angle approximation at work and looking like a wizard.
I do almost everyday as a mechanical engineer. I even do the common angles in my head, which came in handy several times in situations where I’m sailing and something breaks underway etc
I just had to do some “find the angle” geometry this week to quantify some physical stuff that was going on in addition to what the software was causing.
And by “do,” I mean scribbling some triangles to figure out what I was calculating, then throwing the numbers into an online calculator!
Whenever I implement something based on trigonometry, I try around with the different functions until my tests give the expected results.
I use them roughly monthly.
Haha, well in my case high school geometry drew my interest and hyper focus. I will never forget the basic triangle functions/rules.
I actually really enjoyed trig class.
I hated all math classes before it, but I had a great teacher and something about the real-life usefulness (triangulation, navigation, etc) of trig clicked for me and I enjoyed it and made an A.
I fucking failed the shit out of statistics, and hilariously that’s the most related to my real life job, where I’m dealing with gigantic data sets daily looking for outliers/trends.
Stats is the most unintuitive and unpleasant part of math. Trig is a fun problem that nests perfectly into physics
Stats by hand is worse than diff EQ. You are right, it’s so unintuitive. I just let R-Studio decide.
Diff EQ just turns into TOO MUCH FUCKING ALGEBRA at the end though. It’s never that it doesn’t make conceptual sense, it’s just they throw obnoxious integration by parts and fucking fraction decomp.
You never mess up because you didn’t understand the problem/what you were supposed to do. You mess up because you’re supposed to accept that 1/194737 is a perfectly acceptable coefficient to have and there’s no way of telling if you dropped a sign 10 steps ago.
I had an idiot-savant professor that could do Diff EQ in his head, and didn’t understand why all of us couldn’t do it. We would all get D’s and F’s on every test. If was passed down that people have to go to the dean to curve the final grade every semester, and ever semester he would get angry at not being able to fail almost the entire class.
Weird, I find them rather useful. How else do you calculate angles of things?
To check some flat-earthers I recently calculated the angle between an upright person and some skyscrapers 60 miles away.
How often do you need to calculate angles? If I want to know the angle of something I usually measure it.
Especially tan. Fuck tan.
