Date :The DeterminantSquare matrixes have a property called a determinat whena determinant of a matnix is written, it is symbolized byvlrtical bars rather than brocket around the numbers Thisdifferentiates the determinant from a matrix The determinantof matrix is the reduction of the matrix to a singlescalar number. The diferminant of a matrix is found by"expanding" the matrix There are several methods of expandinga matrix and calculating it's determinant. in this lessonwe will only look at a method called "exponsion by minors"Before a large matrix defer minant can be calculated, wemust learn how to calculate the determinant of a 2x2matrix By definition, the determinant of a 2x2 matnixis calculated as Follows :A= abc,d = ad- bcExample: : Find the determinant of A.[62A = - 1 3Solution :A = (6.3-(-1.2)= 18 (-2)= 18 + 2: 20.CSDipindai dengan CamScanner
