Find the Wronskian

  1. Sep 18, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the Wronskian W(t)=W(y1,y2) where I have found y1=1 and y2=(2/9)-(2/9)e^(-9t/2)


    3. The attempt at a solution

    I am not sure how to do the Wronskian. We haven't talked about at all in class and I am not even sure what exactly it does. Any help would be greatly appreciated!

    Thanks,
    Joe

    Re: Wronskian

    The wronskian gives you information about the linear independence of y1 and y2. In spite of the fact it might sound complicated, it's REALLY easy. It's the determinant of a 2x2 matrix of functions. Why don't you look up the definition of wronskian and try it out?

    You're right! The calculation was simple. Thanks!
