1. Rank of Matrix

  • Echelon Form: rank = no. of non-zero rows

  • Normal Form: reduce to identity matrix (I); rank = no. of 1’s on diagonal

2. Matrix Forms

  • Echelon Form: zeros below pivots

  • Normal Form (RREF): pivots = 1 and only non-zero in column

3. System of Equations

  • Form augmented matrix [A|B], row reduce

  • Consistent if no row like [0 0 0 | b≠0]

  • Unique: rank A = rank [A|B] = no. of vars

  • Infinite: rank A = rank [A|B] < no. of vars

  • No soln: rank A ≠ rank [A|B]

4. Linear

2. Key Case Study Themes

Regulation & Deregulation:
Regulation balances safety and cost. Deregulation in 1978 led to lower fares but also industry consolidation and labor issues. NTSB investigates incidents and recommends safety reforms.

Labor & Infrastructure: Events like the 1981 ATC strike show stress and fatigue in aviation labor. Aviation functions as critical infrastructure—yet worker conditions and support are often strained.

Passenger Rights: Emerging in the 1960s–70s consumer

STANDARD HUMAN ESSAY
Thesis: The standard human is a constructed ideal shaped by processes of statistical classification and biopolitical control. Using concepts like l’homme moyen and biopolitics, we can see how bureaucracies and infrastructures defined “normality,” excluded those who didn’t fit, and upheld systems of power that continue to regulate bodies today.
1st Body: Define l’homme moyen (Quetelet’s “average man”) as the origin of statistical norms used to model the “standard

Perspektiv: Sammanförd syn och Intelligent Design

Här ser vi ett tydligt exempel på sammanförd syn, eftersom personen menar att vetenskapliga saker (som syretransport, matematik och kroppens funktion) egentligen redan visar att Gud finns. Det är också ett exempel på Intelligent Design, vilket betyder att man
