Determine the asymptotic stability of the system x' = Ax, where
A is 2x2 matrix, A = alpha beta
gamma delta
( that is. first row is alpha beta, second row is gamma delta)
if it is known that determinant of A, det(A) = alpha*delta - beta*gamma > 0, and that the trace of A, Tr(A) = alpha + delta <0. Here alpha, beta, gamma, and delta are real constants.
