Yn(x)} is linearly independent on a ≤ x ≤ b. 2. The nth-order linear homogeneous differential equation L(y) = 0 always has n linearly independent solutions. ,cn denote arbitrary constants. 3. If the Wronskian of a set of n functions defined on the interval a ≤ x ≤ b is nonzero for at least one point in this interval, then the set of functions is linearly independent there. If the Wronskian is identically zero on this interval and if each of the functions is a solution to the same linear differential equation, then the set of functions is linearly dependent.

A steel ball weighing 128 lb is suspended from a spring, whereupon the spring is stretched 2 ft from its natural length.

1 and simplifying. 2 can be easily obtained by replacing y ′′, y ′, and y by l2, l1, and, l0 = 1, respectively. 1. 1 The characteristic equation of y ′′ + 3 y ′ − 4 y = 0 is l2 + 3l − 4 = 0; the characteristic equation of y ′′ − 2 y ′ + y = 0 is l2 − 2l + 1 = 0. Characteristic equations for differential equations having dependent variables other than y are obtained analogously, by replacing the jth derivative of the dependent variable by l j ( j = 0,1,2). , n). , n). 2. The characteristic equation of y ( 4 ) − 3 y ′′′ + 2 y ′′ − y = 0 is l4 − 3l3 + 2l2 − 1 = 0.
