Use identities to Prove linearly idenpendent

[madking153]

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!

 

[madking153]

that mean any set of vectors contain a 0 cannot be linearly independent ?
not independent but linealy independent

That's what he meant.
