Every linearly dependent set contains the zero vector. linear algebra Determine whether the statement is true or false, and justify your answer. Web· A square matrix A is invertible if and only if det (A) ≠ 0. A matrix that is invertible is often called non-singular and a matrix that is not invertible is often called singular. · If A is a square matrix then: · If A is a square matrix with a row or column of all zeroes then: det (A) = 0 and so A will be singular.
WebThe determinant of any square matrix A is a scalar, denoted det(A). [Non-square matrices do not have determinants.] ... In particular, if any row or column of A is zero then …
WebOf some row of a square matrix consists only of zero entries, then the determinant of the matrix must equal 0. True An upper triangle matrix must be square. True A matrix in which all the entries to the left and below the diagonal entries equal 0 is called a … WebView history. In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an ...
