Sorry, richard: no web page, but perhaps something to start:

 ./ means "HERE"
 ~/ means "HOME"

True, but <grin or groan as appropriate ;>
my learning style is often dependent on examples more than definitions.

[give us examples]

Thought I did ;/


FWIW I studied physics. Theoretical physics. I loved math (still
do). I *always* learnt by examples. Or better even: by alternating
layers of theory and examples. To the point that I'm convinced that
maths is a craft, like pottery or carpentry. You need *practice*.
No practice without examples. But that's just me?

That said, you were so terminant that I just dared to provide
something minimal (not even a theory but just a kind of refcard,
let's call it a theory's skeleton).

Careful you're agreeing with me.
I and my classmates actually learned 1st semester calculus in 2nd semester physics - ie springs and pendulums. There was Part II of my story. Second semester sophomore year all engineers and some math majors took a specific Differential Equations course. It was taught in a different format - 3 lectures and 1 recitation each week. As the number of students required two lecturers and the students were equally divided, one lecture was from engineering and one from the math faculty. Students were randomly assigned, the lectures being in the same hour. The math professor was a pure mathematician {found out later that math grad students competed to take his classes}. The rumor at semester's end was that the engineering professors students' grade distribution was a very normal bell curve. The math professor's distribution was doubled humped. The engineering students average being ~10 points lower.



If you're less terminant next time, I'll provide again examples ;-)
