Discussion Overview

The discussion focuses on determining the linear independence of a set of vectors in the function space F(-∞, ∞), specifically the vectors 0, [cos(πx)]^3, and [sin(3πx)]^5, using appropriate identities.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant asks for help in determining the linear independence of the given set of vectors.
  • Another participant asserts that the presence of the zero vector in any set means that the set cannot be linearly independent.
  • A subsequent participant questions whether any set containing the zero vector is not linearly independent, emphasizing the distinction between "not independent" and "linearly independent."
  • A later reply clarifies the initial statement regarding the zero vector's impact on linear independence.

Areas of Agreement / Disagreement

Participants generally agree that the presence of the zero vector affects linear independence, but there is some confusion regarding the terminology used to describe this relationship.

determine following setd of vectors in F(-infinitity, infinitiy) are linearly independent (using appropriate identities)

0, [cos (pi*x)]^3 , [sin 3*pi*x]^5


pls help !

One of your vectors is 0? A set containing the 0 vector cannot be independent!
 
that mean any set of vectors contain a 0 cannot be linearly independent ?
not independent but linealy independent
 
That's what he meant.
