Wow some of you guys responses make me so mad. I get very offended if someone thinks i'm going to college just to "get a piece of paper for a high paying job"

If I didnt want to go to class, I would happily work at a fast food place full time and live in a ghetto apartment. I don't "study hard for a good future", it's only studying if you don't want to do it and it requires willpower and manning up to do things you dont wanna do.

All of calc is widely used in real life.
Moreover basic classes like calc 3 cover topics and concepts that you need to learn in order to be able to understand pretty much everything in all the upper engineering courses.

For example electrical machinery and power systems use a lot of multivariable calc math relating to electromagnetism, and control systems, signal analysis and telecoms use a lot of complex calc.

You typically don’t get industry employment as a scientist until a PhD because of the specialization. Engineering is another thing, but I’d argue that it doesn’t have the same academic culture. That being said, school definitely shouldn’t be the thing you do to get money. I mean, I guess that sort of thinking is what brings engineering test averages down

You're confusing "basic" with "easy".

Calc 3 is literally a basic class in the sense that is a class that you take early in your career and that the purpose of the class is to give you general tools that you'll use to understand your higher classes.

When I said basic I wasn't making a judgement on the difficulty of calc 3.

But yes, calc 3 is piss easy.

calc 3 is for math/eng/computer majors. Other sci degrees only go to cal 2. Therefore cal 3 is not a basic course. When people say "basic" course in undergrad they mean core curric or level 1/2 courses (bio 1/2, cal 1/2, phys 1/2, American Hist/Gov, Lit 1/2)

Chem majors take diff eq and multi, you can’t really understand p-chem without them and genetics, mathematical bio, economics, finance majors generally take a good amount of prob&stats, analysis and diff eq. CS majors stop taking math courses at Linear Algebra, generally do not have to take analysis or diff eq and take usually 1 introductory math stat course with no probability theory or emphasis on measure. Engineers typically know more maths by the time they graduate than CSniggersz

>> No.11078743

Most will never actually use it though.

Most engineers will work in some low tier desk job being sent pre-designed circuits to edit from either a computer or a senior worker.

Most mathematicians will never work in a job that uses math past 1st year of college if any math at all.

CS majors at various schools have to take calc 3 and various other math classes. Now, I’m not saying it’s the most out there, but also taking an extra class in calculus for differentials isn’t “knowing more math.” Engineers don’t take analysis, either, and judging from the math classes I have taken with them, they’re piss poor even at basic calculation. Your average CS major isn’t much better, but the tryhard CS/math double majors dunk on both of them

The practicality of a subject is a perfectly valid and important question to ask for anyone, even a mathematician. Imagine going to Gauss or Euler and showing them your new math theory. The first question they'll ask about it, of course, is "what is it good for". If it's not good for anything, if it's totally disconnected from all other branches of maths and physics, doesn't help you prove any theorems, of course nobody is going to care about it, and for a good reason. Good mathematics requires direction, and a reason to exist, to be researched. It needs to connect, to be applicable to other areas of study. Only mediocre mathematicians and cranks say otherwise.

If you don't immediately see the utility of studying the rates of change of functions that depend on multiple variables or of being able to parameterize a particles trajectory with a vector equation or what surface or line or volume integrals xo7ld possibly be used for, then there is NO hope for you to ever become a decent scientist/engineer. If you are asking the question at all, you can give up on pure math as well.

CS majors usually take Analysis up to Functional Analysis, Linear Optimization, Combinatorics and Graph Theory, Abstract Algebra up to Galois theory, and linear algebra. This isn't even including the algorithm, complexity, database, networking, programming, and hardware classes that have to be taken.

This is typically taught in undergrad and you can't consider yourself a computer scientist if you don't know this.

But when are you going to use it, OP? and don't say "for my job" because that's a cop out. Real mathematicians grew up using math to better their lives, whether it be game theory to get more popular, coding, physical applications, etc. Nobody does math for muh abstractions. Also ur in multivaribale calc that's not real math i'm a professional (pure) mathematican we never use that shit.
