Let a system of ODES be given by: d % = 56923 l (1%: = _kyl(tl + (1) with k 79 0 and initial conditions 91(0) 2 yo and 92(0) 2 D. 1. Calculate the matrix A, the independent vector 3 and determine the initial value problem in terms of A, l; and the initial condition. 2. Calculate A2, A3, A4 and A5. Formulate the general form of matrix A\" (hint: it has a different form for odd and even exponents). 3. Based on the previous matricw, calculate the exponential matrix eMl of the system and solve the problem. 4. Set 32 ' in part (1). Is the system stable or unstable? (justify your answer)
