Welcome to Yay Math In Studio! The determinants of 2x2 and 3x3 matrices are discussed in this video. The good news is that there are multiple ways to evaluate the determinant of a 3x3 matrix, and each is covered here. Not only do we "determine the determinant" by hand, but the end of the video includes a quick tutorial for how to get the determinant using the TI-84 graphing calculator. YAY MATH!
