Finding the Determinant of a Square Matrix (2×2, 3×3, and 4×4 matrices) [fbt]
This [fbt] video is about finding the determinant of a square matrix using several methods (techniques). Ten (10) examples are shown in this Fort Bend Tutoring video. Determinants are used in various ways when dealing with matrices. 2x2 matrices, 3x3 matrices, and 4x4 matrices are included in this how to find the determinant of matrices video. This lesson has concepts introduced and used in Algebra 2, Precalculus, Calculus, Linear Algebra as well as other courses. Instruction and production is done by Larry "Mr. Whitt" Whittington.
