Interchanging two rows negates the determinant. Scaling a row by a constant multiplies the determinant by that constant. So, now take the matrix A = [− 4 3 3 8 7 3 4 3 3]

WebMar 20, 2024 · I have the determinant of a 4x4 matrix I need to solve for uni. I understand that if a row (or column) is the same then det of a matrix will equal zero, however the rows = the columns in this example. So this rule does not apply. I can not see a way to multiply a row or column to get zeros. WebNow finding the determinant of A (the transformation matrix) is 0. det (A). That is, the determinant of the transformation matrix is 0 and the determinant of the line (if viewed as a long vector) is also zero. Nonetheless, the area below the line may not be zero but the determinant will always be zero. The case gets 🤢 if the function is not linear.
