Hey guys! I need help this this question:
Given that |abcdefghi|=−24, find |adgbehcfi|. I tried constructing a matrix with a determinant of 24 but couldn't find one. Does anyone have ideas?
Look very carefully at the terms on the right-hand side of equations (1) and (2) below. What do you notice?
Oh! That's a really cool. So does that mean if you rotate a matrix, its determinant stays the same?
+116
