funny, I am revisiting rss as a means to escape social media algorithms and doomscrolling. there are lots of good resources in the comments to even further fine tune RSS beyond just being careful about what I subscribe to.
It sounds like a cop-out answer but we also did not specify # of years of experience. We consider all experience levels, so range would be meaningless (like those companies that post 100k - 900k).
I always thought my calculus 1 & 2 courses focused too much on writing solutions without really understanding concepts. I was pretty lost in calculus 3 and 4.
Calculus 3 in the U.S. is multi-variable calculus. Sometimes and introduction to linear algebra is given in this course. Calculus 4 is differential equations. It’s almost never officially called Calculus 4. Sometimes an introduction to linear algebra is given in this course.
Okay that makes sense, that's how the classes went for me in the US, with Calc 3 being multi variable (and as you say, a brush with linear alg via vector-valued functions), and 2 sideways steps from there, one being a course on PDEs and the other on linear algebra, both called by those names rather than listed as a step in the calculus sequence itself.
