The Inside of the funciton :(a)
1) The inside of a Fuction
2) The " Red " Vector a x = -1 : Red Line = 1.41 and It's a Constant reference to the space between functions: Datum Point
3) For me this is Good Stuff
4) One Function " H " is keeping track of functions " P " and " Q " via the Red Line
5) So what that tells me is this : At x = 0 R.L. = 2 ; At x = ? R.L. = 1.41 : Therefor the Function rotates 45 Degrees from 0 to - 1 : that's why Graphics is important.
Good Stuff
