Chapter 5 Videos

Section 5.1

  • Lesson: Review of Systems of Linear Equations (with 1 Solution)

  • Examples: Systems of 3 Linear Equations

  • Lesson: Systems with No Solution or Infinite Solutions

Section 5.2

  • Lesson: Using Matrices and the Gauss-Jordan Method for Solving Systems

  • Lesson: The Gauss-Jordan Method for a System with 3 Equations (and why it matters)

  • Pro-tip: This is kinda hard, I suggest doing the first few problems in MML to practice before you watch the next video!

  • Lesson: The Gauss-Jordan Method and Systems with No Solutions or Infinite Solutions

  • Examples: Using the Gauss-Jordan Method with Larger Matrices (any solution type)

  • Lesson: How to Calculate the Determinant of a Matrix

  • Lesson: The Determinant Theorems

Section 5.5

Section 5.7

  • Lesson: Properties of Matrices: Equality, Addition, Subtraction, and Scalar Multiplication

  • Lesson: Matrix Multiplication

Section 5.8

  • Lesson: Inverse Matrices
