Linear (in)dependent vector sets

  1. Apr 26, 2005 #1
    are 6, 3*(sinx)^2 and 2*(cosx)^2 - linearly independent ?

    Can someone explain how to determine it ?

    What have you tried?

    You might want to make use of the Pythagorean identity (that sin^2(x) + cos^2(x) = 1).

    how i use the identity to solve that problem

    well, what does it mean for things to be linearly independent?
