WebThe determinant of a diagonal matrix is always the product of elements of its principal diagonal. The determinant of an orthogonal matrix is either +1 or -1. The determinant of a matrix can be either positive, negative, or zero. The determinant of matrix is used in Cramer's rule which is used to solve the system of equations. WebAs a hint, I will take the determinant of another 3 by 3 matrix. But it's the exact same process for the 3 by 3 matrix that you're trying to find the determinant of. So here is matrix A.

WebActually both work. the characteristic polynomial is often defined by mathematicians to be det (I [λ] - A) since it turns out nicer. The equation is Ax = λx. Now you can subtract the λx so you have (A - λI)x = 0. but you can also subtract Ax to get (λI - A)x = 0. You can easily check that both are equivalent.
