Cramer's rule uses ratios of these functions to solve linear equations, and if it is equal to zero, a matrix is called "singular."
The Binet-Cauchy multiplication theorem applies to these functions, and the Sylvester theorem about this function was published without a proof. Successive differentiation is used to determine linear independence in the Wronskian type of this function. It can also be broken down to smaller cases by finding the cofactors and related minors. Cramer's rule uses ratios of these functions to solve linear equations, and if it is equal to zero, a matrix is called "singular." For 10 points, identify this quantity, which for a 2 by 2 matrix is given by ad minus bc.
