SUO: Critique Of Dyadic Reason
¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤
In Lieu Of A Beginning, A Teridentical Interlude:
I open an old textbook, selected approximately at random
from off my shelves, and flip to a page, again at random:
| In Exercises 7-16, use Gauss-Jordan elimination
| to solve the given systems of equations.
|
| x - 3y - 6z - 3w = 7
| 3x + 8y + 2z + 4w = 17
| 3x + 12y + 19z - 17w = 22
| 3x + 13y + 25z + 2w = 5
|
| John W. Brown & Donald R. Sherbert,
|'Introductory Linear Algebra',
| Prindle, Weber, & Schmidt,
| Boston, MA, 1984, page 101.
I have no idea whether this system has a solution or not,
nor is it likely that the authors of this textbook meant
for anybodies to exercise themselves on the chance of it,
for, you see, I continued my practice of random selection
right on through the given set of exercises, choosing one
equation each from the sampled Exercises 11, 12, 15, & 16.
And The Moral Of This Random Lesson?
Yet Another Exercise For The Reader.

| Variables are but dummy indices,
| Until some intrepid interpreter
| Nourishes them with a bit'o'wit.
