23. Linear Independence
The chapter elaborates on linear independence within vector spaces, explaining its significance, definitions, criteria, and applications in civil engineering. Key concepts include linear combinations, geometric interpretations, and the use of matrices to determine independence. Applications extend to structural analysis and unique representations in finite element methods.

What we have learnt
- Linear independence is crucial for understanding vector spaces and determining redundancy among vectors.
- A set of vectors is linearly independent if the only solution to their linear combination equating to the zero vector is the trivial solution.
- The rank of a matrix can efficiently determine the linear independence of its column vectors.
Key Concepts
- -- Linear Independence
- A set of vectors is linearly independent if the only way to express the zero vector as a linear combination of them is using all coefficients equal to zero.
- -- Rank of a Matrix
- The rank of a matrix is the maximum number of linearly independent row or column vectors within that matrix.
- -- Wronskian Determinant
- A determinant used to test the linear independence of functions in the context of differential equations.
- -- Homogeneous System of Equations
- An equation system where the right-hand side is zero, used to determine the independence of vectors or functions.
