The given vector functions are solutions to the system x'(t) = Ax(t). 4t e sin (7t) cos (7t) X, = 4 4t X2 cos (7t) X3 sin (7t) 4t e sin (7t) cos (7t) Determine whether the vector functions form a fundamental solution set. Select the correct choice below and fill in the answer box(es) to complete your choice. O A. No, the vector functions do not form a fundamental solution set because the Wronskian is O B. Yes, the vector functions form a fundamental solution set because the Wronskian is The fundamental matrix for the system is
