The matrix, A, is defined by

(a) Calculate the characteristic equation of A. (b) Calculate the eigenvalues of A. (c) Calculate the eigenvectors of A.

An object is subject to two forces, one of 3 N vertically downwards, and one of 8 N horizontally to the right. Draw a diagram representing these two forces as vectors.
