This is a system of two equations with two unknowns. The determinant of the corresponding matrix is the Wronskian. Hence, if the Wronskian is nonzero at some t 0, only the trivial solution exists. Hence they are linearly independent. There is a fascinating relationship between second order linear differential equations and the Wronskian.

The Wronskian. When y 1 and y 2 are the two fundamental solutions of the homogeneous equation. d 2 ydx 2 + p dydx + qy = 0. then the Wronskian W(y 1, y 2) is the determinant of the matrix . So. W(y 1, y 2) = y 1 y 2 ' − y 2 y 1 ' The Wronskian is named after the Polish mathematician and philosopher Józef Hoene-Wronski (1776−1853).
