Use identities to Prove linearly idenpendent

  1. Apr 28, 2005 #1
    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
