WebSep 17, 2024 · Finding the characterestic polynomial means computing the determinant of the matrix A − λIn, whose entries contain the unknown λ. Example 5.2.1 Find the characteristic polynomial of the matrix A = (5 2 2 1). Solution We have f(λ) = det (A − λI2) = det ((5 2 2 1) − (λ 0 0 λ)) = det (5 − λ 2 2 1 − λ) = (5 − λ)(1 − λ) − 2 ⋅ 2 = λ2 − 6λ + 1. WebApr 21, 2015 · 3 Answers. Adding a multiple of one row to another preserves the determinant. Subtract x / d of the last row from the second to get. ( d 0 0 0 0 d d 0 0 0 d d d 0 0 d d d d 0 d d d d d). This is lower triangular, so its determinant is the product of its diagonal, which is d 5.

Now finding the determinant I did: Then: 4 times (− 8 0 5 0) giving 4(0 − 0) = 0 adding the determinants we get 0 + 0 + 0 = 0 So det M1 = 0(1) = 0. WebThe area of the little box starts as 1 1. If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things in, then its determinant is less than 1 1. http://mathcentral.uregina.ca/QQ/database/QQ.09.07/h/rav1.html q-team tournai
