Answer 1

As far as i Know it is used to "solve the system of equations by matrix method.".

eg: Q. "find A−1. Using A−1 solve the system of equations"

It uses, Determinant , transpose of matrix , Adjoint of a matrix. etc

I think ts from Determinant chapter of Mathematics, Class 12th CBSE.

Go & try to learn it from Meritnation.com if you want to.

Answer 2

What you have only one equation. x, y, z need three equations. I do not see any reason for s and to in the matrix formulation.



What you need three equations and their relation with s and t. Then we will be able help you.

Answer 4

type MatrixAddion { public void significant() { int A[][]=new int [10][5]; int B[][]=new int [10][5]; int Sum[][]=new int[10][5]; for(int i=0;i<10;i++) { for(int j=0;j<5;j++) { sum[i][j]=A[i][j]+B[i][j]; } } for(int i=0;i<10;i++) { for(int j=0;j<5;j++) { device.out.println(sum[i][j]+" "); } device.out.println(); } } }
