1. The problem statement, all variables and given/known data Determine if the pair of functions given are linearly independent or linearly dependent on the interval 1<x<∞, and give a reason for your answer. y1=|x| y2=-3x 2. Relevant equations I'm pretty sure this has something to do with the Wronskian. W(f,g)=fg'-f'g 3. The attempt at a solution f=y1, g=y2 f'=1, g'=-3 I can assume that the derivative of the abs. value of x is just 1, because the question says that x is greater than 1, right? So then W(f,g)=-3|x|+3x can i assume x is positive again, so therefore the Wronskian is equal to zero? Would this then make my solution linearly independent? Thanks.
