    Thanks for reposting this. I missed it last year, and as an EE with a misspent youth (I originally got a BA in media), I have frequently struggled with the calculus. One of the few regrets is that I didn’t learn advanced math back when my brain was primed for it. Learning calculus in mid-life is tough.

      On the other hand it's literally never been easier. Seriously, don't so much spend the time learning a discipline as learning to learn with any of the free online LLM tools for any subject and if you've actually got the gumption you'll go far. The 2nd qualification in life is often the toughest but the 3rd and 4th are often the easiest.

    Really great intro to this topic -- rc filtering is rarely explained this intuitively.
