SUMMARY

An inconsistent underdetermined system consists of two equations with three unknowns that do not intersect, resulting in no solutions. The discussion clarifies that "inconsistent" indicates the absence of solutions, while "underdetermined" refers to having fewer equations than unknowns. A practical example provided is the intersection of two offset parallel planes, which illustrates the concept effectively.

PREREQUISITES
  • Understanding of linear algebra concepts, specifically systems of equations.
  • Familiarity with the definitions of consistent and inconsistent systems.
  • Knowledge of underdetermined systems and their characteristics.
  • Basic comprehension of geometric interpretations of equations in three-dimensional space.
NEXT STEPS
  • Study the properties of inconsistent systems in linear algebra.
  • Explore examples of underdetermined systems with practical applications.
  • Learn about the geometric representation of equations in three dimensions.
  • Investigate methods for solving systems of equations, including parametric solutions.
USEFUL FOR

Students studying linear algebra, educators teaching systems of equations, and anyone interested in understanding the complexities of inconsistent and underdetermined systems.

Homework Statement


Give an example of an inconsistent underdetermined system of two equations in three unknowns.


Homework Equations





The Attempt at a Solution


I'm confused as to what the question is asking for. Doesn't inconsistent mean that the system has no solution while underdetermined means the system has many solutions defined parametrically? The two definitions seem to contradict here.

i think in this context underdetermined means less equations than unknowns, and inconsistent, means there are no solutions

an example might be finding the intersection of two offset parallel planes?
 
that makes the problem much more doable. thanks :)
