2 After learning These impressions you can expect 1. Describing the matrix 2. Applying the concept of similarity of two matrices 3. Able to addjaction and substraction of matrices

3 Students Presence Class XII: February 2010 CHECK TABLE Name SickPermissi on Without Notice Agus 013 Budi 120 Cicha 511 Deni 202 Name cotton Drillsilk A B Cloth price data in A and B Stores (In thousands) / m Name SickPermissi on Without Notice Agus 013 Budi 120 Cicha 511 Deni 202

4 The composition of rectangular numbers arranged in rows and columns, written between regular or square brackets What is matrix ? Row 1 Row 2 Row 3 Row 4 Column 1Column 2 Column 3 Matrix has four rows and three columns say Order 4 x 3 matrix If a matrix has m rows and n columns is called Order m x n matrix Conclusion Numbers referred to the constituent elements of the matrix element that

5 How about this matrix? How many rows ? How many columns ? So…. The order is ? 2 x 3

6 What do you thing about these two matrices? Matrix A = matrix B Matrix R = matrix S Matrix P  matrix Q What conclusions?Two matrices is called equal if: Same order Elements that on the two matrices has the same value SIMILARITY OF TWO MATRIX

7 dan B = A = x – 7 = 6 If matrix A = matrix B, then determine value of x and y ! 1. Given matrix So, x = = 13 2y = -1So y = – ½

8 From Example Simplify + = + = Ans: Addition and Subtraction of Matrices Matrices of the same order are added by summing up the corresponding elements.

9 Matrices of the same order are subtracted by taking the difference of the corresponding elements. From Example Simplify − = Ans: _ =
