Lines are absolute value. Double lines is the smoking gun. Link to try to explain better than me. One set of lines.... -2 = 2. Double lines is vector related..and a little farther than I went in engineering.
I don't know enough math, but I was able to find out the ||x|| notation refers to "a norm" and with the infinity subscript that's the infiniry norm / uniform norm:
neither do I. But the cliff dive into calculus is the functions to calculate where a line is going. What is it approaching is the socratic methodology. What stands out to me is the multiple mentions of this being common in vector absolute value would indicate a formula (as I would see it close to a PID formula proportional/derivative/integral) of absolute value of a projection. Rate of increase or something. I have no degree, but I've dealt with things like PID and of this sort in the real world that have left me confused why 3 yrs of engineering never touched on any of it.
Can a math nerd explain wtf we're looking at here?
