From electronics, mechanical, or civil engineering, architecture, chemistry, even trades like carpentry or general contracting require math. At least a working ability at algebra and geometry is extremely helpful if not required. (Real) programmers need math, and often I use math beyond basic arithmetic in my daily life to solve problems or make plans.

I didn't learn any thermodynamics, kinematics, or fluid mechanics outside of my classroom though. It's far more helpful to me anyway

What I meant with the partial was that there are some sections of math; algebra, integrals, eigen vectors and values, Marcov chains, etc; that I've found useful so far in programming. But the applications of these things wasn't taught in math class, it was taught in classes like CSCI 35000 which teach about the math used in programming and classes after that teach you how apply it to your specific field such as cybersecurity and game design.

We use it, just not how it's taught in that class. Not saying the class is useless, just saying it's a base requirement to knowing what to do.

physics in particular I found far more helpful in my daily life than differential equations or calc; but I wouldn't be able to do those physics problems without algebra or geometry; so, for me, those two are, without a doubt indispensable.

The way the physics class used derivatives, like acceleration/velocity was taught differently from how my calc class taught it. My HS physics was actually harder than my college physics; the college physics was WAY more about vectors and being able to take a little bit of information and find the correct formula, then re-arrange the formula so you get the answer faster. I can't ever encountering limits in either physics class either.

give me an example of a boundary equation <_< you have me curious.

It's physics 2 not physics 1, I switched from Mechanical engineering before going to computer science and I took that class. It was hard as hell (not the reason I switched though) but basically thirdi is referring to magnetic field equations. It's commonly integrated when testing the curve of a magnetic object going through an oppositely charged magnetic field, common example being an electron through a positive magnetic field, or even the magnetic field produced by a wire with a flow of electrons.

Yeah exactly, it wasn't core for my ME classes, so I was exposed to it and that was mainly it, but basically you are given a boundary condition as a closed or open surface and you use single and double integrals to determine for example the magnetic flux through it. It's complicated to explain and I'd be a liar if I said I was an expert and said it was easy lol.

It’s basically a type of differential equation where we place known boundaries to guide our answer.
The boundary condition acts on an integer. There are all sorts of applications, from how liquid may travel through a path, diminishing ground at a point, measuring the potential charge or current in an area none is present, or here is a simple one: Someone at the gym is doing the wavy rope thing. They hold one end of the rope, the other is secured to a metal frame. They move their hands up and down making waves (causing oscillations) in the rope. If I needed to describe the rope to perform a calculation on it- I’d likely need to consider the fact that both ends have 0 movement (to our spec tolerance for movement) and thus knowing the ends effectively done move, I would set boundary conditions for the ends:
V(x=0)=0 V(x=L)=0. Picture using math to describe a dog to someone who’d never seen one. Just math, no other words.

Lol. For an ME that’s going to likely be your number one use. Electrical engineers could make some other uses of it- but let’s be honest, those guys are just weird.

It's an exposure thing. Every student is potentially the next genius revolutionary mathematician. Sometimes you don't know you like something or are good at it until you try it. You don't want the next calculus to never be invented because the person who would've done it didn't know that math theory was a field. All the rest of us who never use it are just casualties in the quest to ensure that no one misses their chance through lack of exposure and experience.
(Doesn't make it any less frustrating when you end up not being the savior of the math universe and want to do something that just needs normal math, though...)
