SUMMARY

The discussion focuses on finding the orthogonal complement of the span of the vectors [0, 0, 1, 0] and [2, -1, 0, 1]. To determine the orthogonal complement, one must establish that any vector in this complement is orthogonal to both given vectors. This is achieved by setting up dot product equations that equal zero, resulting in a system of equations that can be solved to find a basis for the orthogonal complement.

PREREQUISITES
  • Understanding of vector spaces and spans
  • Knowledge of dot products and orthogonality
  • Familiarity with solving systems of linear equations
  • Basic linear algebra concepts, including basis and dimension
NEXT STEPS
  • Learn how to compute the dot product of vectors in linear algebra
  • Study methods for solving systems of linear equations
  • Explore the concept of basis and dimension in vector spaces
  • Investigate the geometric interpretation of orthogonal complements
USEFUL FOR

Students studying linear algebra, educators teaching vector spaces, and anyone looking to deepen their understanding of orthogonality in mathematical contexts.

Homework Statement



Find the orthogonal complement.

Homework Equations



span {[0 0 1 0] [2 -1 0 1]} transpose


The Attempt at a Solution



I'm really confused on this. I've tried setting up things like this:

[0 0 1 0] [2 -1 0 1] [x y z v] transpose = [0 0 0 0] transpose

But, I'm not sure where to go from here...all the examples I see having two column matrices...not split up like in this problem...

Any vector <x, y, z, v> in the orth. complement has to be orthogonal to (perpendicular to) each of the two vectors in your set. The dot product of each of your two given vectors with <x, y, z, v> will be zero. That will give you two equations in four unknowns, from which you can find two vectors that form a basis for the orthogonal complement.
