How to understand calculus in an hour


I just ran across this simple explanation by Miles Mathis of what calculus really is.  It is quite simple, even if the author is a bit long winded and self congratulatory.  Check it out.

Here's a TL;DR extract of the important bit.  Please note that everything is a length, not just a point or a number.

------------------------

1            Δz           1, 2, 3, 4, 5, 6, 7, 8, 9….
2           Δ2z            2, 4, 6, 8, 10, 12, 14, 16, 18….
3            Δz
2           1, 4, 9, 16, 25, 36, 49 64, 81
4            Δz
3           1, 8, 27, 64, 125, 216, 343
5            Δz
4            1, 16, 81, 256, 625, 1296
6            Δz
5            1, 32, 243, 1024, 3125, 7776, 16807
7            ΔΔz           1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1
8            ΔΔ2z            2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2
9            ΔΔz
2           1, 3, 5, 7, 9, 11, 13, 15, 17, 19
10            ΔΔz
3            1, 7, 19, 37, 61, 91, 127
11            ΔΔz
4            1, 15, 65, 175, 369, 671
12            ΔΔz
5            1, 31, 211, 781, 2101, 4651, 9031
13            ΔΔΔz            0, 0, 0, 0, 0, 0, 0
14            ΔΔΔz
2            2, 2, 2, 2, 2, 2, 2, 2, 2, 2
15            ΔΔΔz
3            6, 12, 18, 24, 30, 36, 42
16            ΔΔΔz
4            14, 50, 110, 194, 302
17            ΔΔΔz
5           30, 180, 570, 1320, 2550, 4380
18            ΔΔΔΔz
3            6, 6, 6, 6, 6, 6, 6, 6
19            ΔΔΔΔz
4            36, 60, 84, 108
20            ΔΔΔΔz
5            150, 390, 750, 1230, 1830
21            ΔΔΔΔΔz
4           24, 24, 24, 24
22            ΔΔΔΔΔz
5           240, 360, 480, 600
23            ΔΔΔΔΔΔz
5            120, 120, 120
      from this, one can predict that
24            ΔΔΔΔΔΔΔz
6           720, 720, 720
     And so on.

Again, this is what you call simple number analysis. It is a table of differentials. The first line is a list of the potential integer lengths of an object, and a length is a differential. It is also a list of the integers, as I said. After that it is easy to follow my method. It is easy until you get to line 24, where I say, “One can predict that. . . .” Do you see how I came to that conclusion? I did it by pulling out the lines where the differential became constant.
7      ΔΔz       1, 1, 1, 1, 1, 1, 1
14       ΔΔΔz
2      2, 2, 2, 2, 2, 2, 2
18       ΔΔΔΔz
3      6, 6, 6, 6, 6, 6, 6
21       ΔΔΔΔΔz
4       24, 24, 24, 24
23       ΔΔΔΔΔΔz
5       120, 120, 120
24       ΔΔΔΔΔΔΔz
6       720, 720, 720

Do you see it now?
2ΔΔz = ΔΔΔz
2
3ΔΔΔz
2 = ΔΔΔΔz3
4ΔΔΔΔz
3 = ΔΔΔΔΔz4
5ΔΔΔΔΔz
4 = ΔΔΔΔΔΔz5
6ΔΔΔΔΔΔz
5 = ΔΔΔΔΔΔΔz6

All these equations are equivalent to the magic equation, y’ = nx
n-1. In any of those equations, all we have to do is let x equal the right side and y’ equal the left side. No matter what exponents we use, the equation will always resolve into our magic equation.

  1. I'm afraid you lost me at the rate of change of the rate of change of Z (#7)
