characteristic polynomial calculator
As we explained in the first section we need to calculate the determinant of We have 2-λ 3-λ - 3 4 λ² - 5λ - 6 Alternatively we might have computed tr A 2 3 5 and det A 2 3 - 3 4 -6. This eigenspace calculator finds the eigenspace that is associated with each characteristic polynomial.
Multiplicity
The coefficients of the polynomial are determined by the determinant and trace of the matrix.
. Characteristic polynomial In linear algebra the characteristic polynomial of a square matrix is a polynomial which is invariant under matrix similarity and has the eigenvalues as roots. 1 By using the quadratic formula we can find the Eigenvalue λ. λ12 tracetrace2 4determinant 2 λ 1 2 trace trace 2 - 4 determinant 2.
The characteristic polynomial CP of an nxn matrix A A is a polynomial whose roots are the eigenvalues of the matrix A A. This calculator computes eigenvalues of a square matrix using the characteristic polynomial. If A is an n n matrix then the characteristic polynomial f λ has degree n by the above theoremWhen n 2 one can use the quadratic formula to find the roots of f λ.
For a 2x2 matrix the characteristic polynomial is λ2 traceλ determinant λ 2 - trace λ determinant so the eigenvalues λ12 λ 1 2 are given by the quadratic formula. Hence λ 6 36 4 2 λ 3 22. There exist algebraic formulas for the roots of cubic and quartic polynomials but these are generally too cumbersome to apply by hand.
