WebIt is easy to compute the determinant of an upper- or lower-triangular matrix; this makes it easy to find its eigenvalues as well. Corollary If A is an upper- or lower-triangular matrix, … WebCalculate its determinant using the characteristic equation. This determinant is the characteristic polynomial which is a quadratic equation for the case in which A A A is a 2x2 matrix. Use the quadratic formula to solve for λ \lambda λ from the quadratic equation. Thus we start following the steps and calculate the matrix subtraction: flag search by image
