How to determine if matrices are linearly independent

Answer: Many variants: Write the coefficients in a matrix (rows or columns, it does not matter, either all rows or all columns). Check that the rank of the matrix is equal to the number of polynomials. This can be done by either using the Gauss. Expert Answer. Thus. we get equation Ax=0 has not only trivial solution, the columns of the matrix form a linearly dependent set. Say we have the transformation matrix of full rank such that consists of linearly independent vectors which aren't orthogonal to each other, a vector v, and the orthonormalized transformation matrix. − 2 π ≤ θ < 0.. Alternatively if you have a matrix [math]A [/math] where columns are the coefficients of the polynomials then take [math]\det (A^TA) [/math]. The system is linearly independent iff the determinant is non-zero. For example, take the polynomials [math]1+x, x+x^2, x^2+x^3 [/math] The matrix is. Determining Linear Independence By row reducing a coefficient matrix created from our vectors { }, we can determine our < >.
