Find the Wronskian: Solve for W(t) with y1=1 and y2=(2/9)-(2/9)e^(-9t/2)

Homework Statement

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

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

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!
