I mean all STEM need to take introductory physics because they will need to understand the basics of how the world works. You can't understand Classical Mechanics and Electromagnetism without calculus.

Now there are many universities and majors which will give you physics before calculus (forgetting that the original argument were in reverse) or will give some majors what is called Algebra based physics. Which is kind of trust me these are the equations to solve this problem, you just need to solve this algebraic manipulation of numbers. So if I give you any physics problem that requires any further manipulation or derivation then you will realize you did not understand physics well.

There is also benefits of studying calculus in itself. For example, a lot of optimization techniques that is being used by programmers and ML are rooted from calculus methods.

>All people who took calculus because they had to, how have you used it?

Although I create software, my degree is in finance. Calculus is everywhere, and I mean everywhere, in finance after you get past the basic intro courses, for school at least. However, in real life I have only used it not that often and mostly related to machine learning and optimization. Even then, I didn't do it by hand, I just knew what to do and let computers calculate the rest.

I once used it to get reimbursed properly for local salary taxes I had to pay while at a job site.

Converging series. Shocked the scumbag HR guy into submission
