Question

How do you use the Wronskian with DEs?
lets say there is
y''+y'p(x)+yq(x)=0
What will be the Wronskian here and what does that actually mean?

Answer 1

let y1 and y2 be the solutions to te differential equation

=y1y2' - y2y1'
if wronskian=0 then y1 and y2 are dependent'
if wronskian does not =0 then y1 and y2 are independent
