WebApr 9, 2024 · 1,207. is the condition that the determinant must be positive. This is necessary for two positive eigenvalues, but it is not sufficient: A positive determinant is also consistent with two negative eigenvalues. So clearly something further is required. The characteristic equation of a 2x2 matrix is For a symmetric matrix we have showing that the ... WebSolution: The given matrix is a 2 x 2 matrix, and hence it is easy to find the inverse of this square matrix. First we need to find the determinant of this matrix, and then find the adjoint of this matrix, to find the inverse of the matrix. B = ⎡ ⎢⎣2 4 3 5⎤ ⎥⎦ B = [ 2 4 3 5] det B = B = 2 x 5 - 4 x 3 = 10 - 12 = -2.
