Student Outcomes

  • Students represent complicated systems of equations, including 4×4 and 5×5 systems of equations, using matrix equations in the form Ax = b, where A represents the coefficient matrix, x is the solution to the system, and b represents the constant matrix.
  • Students use technology to calculate the inverse of matrices and use inverse matrix operations to solve complex systems of equations.
