The Determinant and Inverse of a Matrix on Casio Classwiz fx-991EX | fx-570EX Calculator

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at finding and working with the determinant and inverse of both a 2 x 2 and a 3 x 3 matrix. We discover how to easily find the determinant and also use it to display the inverse in a different form than given by the calculator. We also confirm a matrix multiplied by its inverse gives the identity matrix.
