I was going through a simple proof written for the existence of supremum. When I tried to write a small example for the argument used in the proof, I got stuck. The proof is presented in Vector Calculus, Linear Algebra, And Differential Forms written by Hubbard. Here is the theorem.
Theorem: Every non-empty subset X R that has an upper bound has a least upper bound ( s u p X ).
Proof: Suppose we have x X and x 0. Also, suppose α is a given upper bound.
If x α, then there is a first j such that j t h digit of x is smaller than the j t h of α. Consider all the numbers in [ x , a ] that can be written using only j digits after the decimal, then all zeros. Let b j bt the largest which is not an upper bound. Now, consider the set of numbers [ b j , a ] that have only j + 1 digits after the decimal points, then all zeros.
The proof continues until getting b which is not an upper bound.
Now, let's assume that X = { 0.5 , 2 , 2.5 , , 3.23 } where 3.23 is the largest value in the set and α = 6.2. I select 2 as my x. Then, the value of j is one. Hence, the set is defined as [2.1,2.2.,⋯,2.9,6.2]. In this case, b j is 2.9.
If create a new set based on b j , doesn't that become [2.91,2.92.,⋯,2.99,6.2]. If so, b j + 1 = 2.99 and I'd just add extra digits behind this number. In other words, I'd never go to the next level. I am probably misinterpreting the proof statement.
Two important details after receiving some comments are as follows.
1. "By definition, the set of real numbers is the set of infinite decimals: expressions like 2.95765392045756..., preceded by a plus or a minus sign (in practice the plus sign is usually omitted). The number that you usually think of as 3 is the infinite decimal 3.0000... , ending in all zeroes."
2. "The least upper bound property of the reals is often taken as an axiom; indeed, it characterizes the real numbers, and it sits at the foundation of every theorem in calculus. However, at least with the description above of the reals, it is a theorem, not an axiom."

To calculate:To check if (fg)(x)=(gf)(x). Professor Harsh gave a test to his college algebra class and nobody got more than 80 points (out of 100) on the test. One problem worth 8 points had insufficient data, so nobody could solve that problem.
The professor adjusted the grades for the class by
a. Increasing everyone's score by 10% and
b. Giving everyone 8 bonus points
c. x represents the original score of a student

I understand the process for how Eigenvalues are involved in Differential Equations. If you have Differential System of Equations like this
x = ( 2 1 0 1 ) x
The solution to that System of Differential Equations is a Linear Combination of e to the power of the eigenvalues times the corresponding eigenvectors.
x = C 1 e 2 t ( 1 0 ) + C 2 e t ( 1 1 )
However, what I am struggling with figuring out how Generalized Eigenvalues translate to the solutions in Differential Equations. If you take this System of Differential Equations
x = ( 1 0 0 3 1 0 6 3 1 ) x
The solution to this Differential Equations is
x = C 1 e t ( 1 3 t 6 t + 9 2 t 2 ) + C 2 e t ( 0 1 3 t ) + C 3 e t ( 0 0 1 )
But the eigenvectors of this matrix (including the generalized eigenvectors) are
v 1 = ( 0 0 1 ) , w 1 = ( 0 1 3 ) , w 2 = ( 1 1 3 )
These eigenvectors do share some similarities to the solution to the System of Equations. However, the
6 t + 9 2 t 2
term in the solution is one I have no idea how generalized eigenvectors relate. May someone please explain how these eigenvectors translate into Differential Equations?
