Basis (linear algebra)

https://math.stackexchange.com/questions/251509/basis-linear-algebra

It's important to remember that a vector w written in terms of basis \alpha = \{v_1, v_2, v_3, v_4\} has the form: ( a, b, c, d)_{\alpha} = av_1 + bv_2 + cv_3 + dv_4 It's also important to ...

A determinant problem

https://math.stackexchange.com/questions/941616/a-determinant-problem

Let g(x) = (x-1)(x-\alpha)(x-\beta), a monic polynomial with the roots 1, \alpha, \beta. Then the Vandermonde matrix of roots to g is M = \left(\begin{array}{ccc}1 & 1 & 1\\1 & \alpha & \alpha^2\\ 1 & \beta & \beta^2\end{array}\right) ...

Orthongonally diagonalize the matrix A

https://math.stackexchange.com/questions/1773428/orthongonally-diagonalize-the-matrix-a

Solve the systems of equations in each step, i.e. find bases for the solution sets. Then use the Gramm-Schmidt procedure to turn these bases into orthonormal ones. In this case, each eigenspace has ...

Eigenvalues of a companion matrix

https://math.stackexchange.com/questions/1375278/eigenvalues-of-a-companion-matrix

\lambda is a root of the characteristic polynomial x^2 + ax + b, hence -a\lambda-b=\lambda^2, and you are done.

A conjecture regarding the eigenvalues of real symmetric matrices

https://math.stackexchange.com/questions/2451278/a-conjecture-regarding-the-eigenvalues-of-real-symmetric-matrices

The result can be proven using the same arguments as in the proof that the eigenvalues of symmetric matrices are real. Let x\ne0 solve Mx=\lambda Dx for some possibly complex \lambda. If Dx=0 ...
