The vectors a1,, an are called linearly independent if there are no non-trivial combination of these vectors equal to the zero vector. That is, the vector a1,, an are linearly independent if x1a1 + + xnan = 0 if and only if x1 = 0,, xn = 0.

To test for linear independence, let c 1 e x + c 2 e − x = 0 Where c 1 and c 2 must equal 0 for the two functions to be demonstrated to be linearly independent. So for x = 0:

(t  To determine whether a set S of vectors is linearly independent, you form a matrix which has those vectors as columns, and you calculate its reduced row echelon  5 Oct 2015 In this note, we provide details proving that a positively linearly independent set in \mathbb {R}^n for n \in \{1, 2\} has at most 2n elements, but a  Linear dependence and independence are based on whether or not there is more than one solution to a system of equations. In this lesson, we'll look 13 Oct 2011 Definition 2.2. A linearly independent spanning set is called a basis of r.

Problem 549. By calculating the Wronskian, determine whether the set of exponential functions \[\{e^x, e^{2x}, e^{3x}\}\] is linearly independent on the interval $[-1, 1]$. Add to solve later. Sponsored Links

then the matrix A is symmetric. This is a very important notion, and we give it its own name of linear independence. A set of non-zero vectors {→u1, ⋯, →uk} in Rn is said to be linearly independent if whenever k ∑ i = 1ai→ui = →0 it follows that each ai = 0. Note also that we require all vectors to be non-zero to form a linearly independent set.

Determine a second linearly independent solution to the differential equation y ″ + 6y ′ + 9y = 0 given that y 1 = e −3t is a solution. Solution. First we identify the functions p(t) = 6 and f(t) = e −3t. Then we determine the function v(t) so that y 2 (t) = v(t)f(t) is a second linearly independent solution of the equation with the formula Therefore, y 1 = e x is not a constant multiple of y 2 = x; these two functions are linearly independent.

The set of functions {1, x, sin x, 3sin x, cos x} is not linearly independent on [−1, 1] since 3sin x is a mulitple of sin x. Thus, selection of constants c 1 = 0, c 2 = 0, c 3 = 3, c 4 = −1, and c 5 = 0 results in the following:
