In mathematics, the Wronskian (or Wrońskian) is a determinant introduced by Józef Hoene-Wroński (1812) and named by Thomas Muir (1882, Chapter XVIII). It is used in the study of differential equations, where it can sometimes show linear independence in a set of solutions. WebSo since the Wronskian is equal to zero, this means that this set of solutions we call f (x) f (x) and g (x) g(x) do not form a fundamental set of solutions. In this particular case it is very easy to prove how these two functions are linearly dependent, if we go back to look at them: Equation 4: Preliminary solutions for a differential equation
