SECOND-ORDER LINEAR DIFFERENTIAL EQUATIONS
nd-Order ODE - 8 2.2 Linear Independence Two functions, y 1 (x) and y 2 (x), are linearly independent on an interval [x 0, x 1] whenever the relation c 1 y 1 (x) + c 2 y 2 (x) = 0 for all x in the interval implies that c 1 = c 2 = 0. Otherwise, they are linearly dependent. There is an easier way to see if two functions y 1 and y 2
