olve the following set of coupled differential equations using the matrix methods discussed in class. SHOW YOUR WORK. (12 points) dx/dt = x + 4y dyldt = 2x + 3y x(0) = 2, y(0)=1 The eigenvalues of the matrix A are ) = -1 and + 5. The matrix of the eigenvectors for 2. =-1 (left column) and 2 = +5 (right column is V= =(-1/2 1)
