We have Ak + 1 = AkA = [1 1 2k − 1 0 0 1 0 0 1][1 1 1 0 0 1 0 0 1] by the induction hypothesis = [1 1 2k + 1 0 0 1 0 0 1] = [1 1 2(k + 1) − 1 0 0 1 0 0 1]. Thus the formula holds for n = k + 1. Hence the formula is true for any positive integer n by induction. Click here if solved 99 Tweet Add to solve later

The above identities concerning the determinant of products and inverses of matrices imply that similar matrices have the same determinant: two matrices A and B are similar, if there exists an invertible matrix X such that A = X BX. Indeed, repeatedly applying the above identities yields The determinant is therefore also called a similarity invariant. The determinant … WebThe n-volume of an n-parallelepiped formed by n vectors in ℝ n is the absolute value of the determinant of these n vectors. When a square matrix A is considered as a …

The point of the characteristic polynomial is that we can use it to compute eigenvalues. Theorem 5.2.1: Eigenvalues are Roots of the Characteristic …
WebDeterminants take a square matrix as the input and return a single number as its output. Determinants Definition. For every square matrix, C = [\(c_{ij}\)] of order n×n, a determinant can be defined as a scalar value that is real or a complex number, where \(c_{ij}\) is the (i, j) th element of matrix C. WebIn linear algebra, the Cayley–Hamilton theorem (named after the mathematicians Arthur Cayley and William Rowan Hamilton) states that every square matrix over a commutative ring (such as the real or complex numbers or the integers) satisfies its own characteristic equation..
