What values of t make the homogenous system dependent?

Click For Summary
SUMMARY

The discussion focuses on determining the values of t that make the homogeneous system of equations dependent. The equations given are (4-t)x + y = 0 and 2x + (3-t)y = 0. It is established that t = 2 is one value that results in a dependent system, while t = 4 and t = 3 lead to trivial (zero) solutions. The challenge remains to identify a second value of t that also makes the system dependent.

PREREQUISITES
  • Understanding of linear algebra concepts, specifically homogeneous systems of equations.
  • Familiarity with the concept of dependency in systems of equations.
  • Knowledge of how to manipulate and solve linear equations.
  • Ability to identify nonzero solutions in a homogeneous system.
NEXT STEPS
  • Research the conditions for linear dependence in homogeneous systems of equations.
  • Study the method of determining values of parameters that yield nontrivial solutions.
  • Explore the implications of the determinant of the coefficient matrix in relation to dependency.
  • Learn how to apply the rank-nullity theorem to analyze homogeneous systems.
USEFUL FOR

Students studying linear algebra, educators teaching systems of equations, and anyone seeking to deepen their understanding of homogeneous systems and their properties.

Homework Statement


Consider the homogenous system:
[tex]L_1 \rightarrow (4-t)x + y = 0[/tex]
[tex]L_2 \rightarrow 2x + (3 -t)y = 0[/tex]

Find two values of t that make the system dependent.
For each value of t, find a nonzero solution to the the system.

Homework Equations


The Attempt at a Solution


You can't use t = 4 or t = 3 because it will lead to a zero solution.
I have found one of the values is t = 2, but I can't seem to find another value for t that makes the system dependent.

Try filling in step 2. What equation can you give which will define the propoerty of making the system dependent?
