Derivative of wronskian

Webdiscovered a nice formula which relates the Wronskian W(x) for di erent values of x. Abel’s formula says W(x 1) = W(x 0)e 1 R x x0 p 1(x)dx; and he found this by rst showing that the Wronskian satis es a rst order di er-ential equation dW(x) dx = p 1(x)W(x); known as Abel’s di erential equation. 3. Two examples 3.1. Example WebProposition 1. If f and g are two di erentiable functions whose Wronskian is nonzero at any point, then they are linearly independent. Proof.
