I’ve often thought it very unfortunate that we leave calculus so late in K-12 education, and for some students never get there at all (at least in my country). I remember spending most of my childhood mystified about what this mysterious “calculus” thing was, and then finally getting around to learning it and saying “oh, it’s just that?”

And then once students are initiated into the (disappointing) mysteries of calculus, what next? They spend the next few years mechanically carrying out analytic differentiations and integrations of a bunch of ever-more-artificial one-dimensional functions. Do you know what the integral of tanh (x + x^x) is? You shouldn’t, because it doesn’t fricking matter! Most of the actually useful integrals that anyone would ever calculate in real life turn out to be only solvable numerically.

In conclusion, put an introduction to the intuitive ideas behind calculus earlier (Year 7), emphasise numerical over analytic solutions, and use the time saved to move on to things like multivariable calculus (and path integrals, which I still don’t understand properly).



Which path integral?

https://en.wikipedia.org/wiki/Path_integral

Path integral may refer to:

Line integral, the integral of a function along a curve

Functional integration, the integral of a functional over a space of curves

Path integral formulation by Richard Feynman of quantum mechanics


We’re talking about basic calculus, so it’s the first one.


I'd be inclined to agree, but parent poster was concerned about solving problems numerically, which is trivial for line integrals, as they are just sums of triangle hypotenuses.


Functionally I see many non math people struggle to understand rate of change.

I find integrals useful.

Also I see my computer science pals have a lack of faith in math. I don't understand why.


What do you mean by lack of faith? Not trusting mathematical proofs?


I can't speak for GP, but I'd speculate "lack of faith that understanding the math behind computer science will provide any real value as a programmer".


Ah, then I'm right behind. But it's not that more Math knowledge wouldn't help at all, just that the cost to benefit ratio seems not worth it.

I never needed actual Math in my career so far.
