Question
eigenvalues of [[0, 1], [-1, 0]]
Answer
-
Find the characteristic equation. The characteristic equation is given by
, where is the matrix, represents the eigenvalues, and is the identity matrix. In our case,and . So, . The determinant of this matrix is. Therefore, the characteristic equation is. -
Solve for
. We have the equation . Subtracting 1 from both sides gives . Taking the square root of both sides gives .
