does every matrix have a square root The question is equivalent to asking if all polynomials have roots Every square matrix has a characteristic polynomial In the domain of real numbers not every polynomial
Trace and determinant are both positive so both eigenvalues are positive So if you can diagonalize the diagonal form will have a square root QAQ 1 D P 2 where Q is Square root of a matrix definition and calculation using eigenvalues What does it mean for a matrix to have a square root Check out my Eigenvalues playlist
