2. Click the “Calculate” button.
3. Your result will display whether the vectors are linearly independent or dependent.
4. Utilize the provided explanations for better comprehension.

Formula

The determination of linear independence can be done through several methods, but the most common involves the concept of a matrix. Given a set of vectors v₁, v₂, …, vₖ, you can form a matrix:

A = [v₁ v₂ … vₖ]

To check for linear independence, you can compute the determinant of the matrix A:

If det(A) ≠ 0, then the vectors are linearly independent.
If det(A) = 0, then the vectors are linearly dependent.

Example Calculation

Consider the vectors:

• v₁ = (1, 2, 3)
• v₂ = (4, 5, 6)
• v₃ = (7, 8, 9)

We construct the matrix A:

A = [1 4 7; 2 5 8; 3 6 9]

Calculating the determinant:

Here, det(A) = 0, thus the vectors are linearly dependent.
