In this lesson on Determinants, you will learn the basics of a determinant such as the requirement of square matrices and using vertical bars to differentiate them from standard matrices. You will then move onto finding the second order determinant of a 2x2 matrix before moving into finding the third order determinant of a 3x3 matrix. For a 3x3 matrix you first learn the technique called expansion by minors before moving into the diagonal method. Four examples at the end test your new found knowledge.
