  1. 1. a ... is the number you get when you subtract the column and row of a given element in a rectangular or square matrix
  2. 4. it is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints
  3. 7. a ..... matrix is a matrix that has an equal number of rows and columns
  4. 8. the elements on the main diagonal are multiplied and subtracted from the product of the other elements(if 2x2 matrix)
  5. 9. the scalar is usually denoted by and is called an eigenvalue of A,and the nonzero column matrix x is called an ...of A corresponding to lambda
  6. 11. find the z by the gaus-jordan method 2X+y+2z=10 x+2y+z=8 3x+y-z=2

  1. 2. the ..... of a matrix is found by interchanging its rows into columns or columns into rows
  2. 3. it is a nonzero vector that can be changed at most by its scalar factor after the application of linear transformations
  3. 5. an arrangement of numbers, symbols, etc. in rows and columns, treated as a single quantity
  4. 6. to define the determinant of a matrix of order higher than 2,it is convenient to use the notions of ... and cofactors
  5. 10. Find the determinant a=(020)(3-21)(13-1)
