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.. If A is a given n × n matrix and I n is the n × n identity matrix, then the … WebUsing the definition of a determinant you can see that the determinant of a rotation matrix is cos 2 ( θ) + sin 2 ( θ) which equals 1. A geometric interpretation would be that the area does not change, this is clear because the matrix is merely rotating the picture and not distorting it in any other way.

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.
