Write the given second order equation as its equivalent system of first order equations. u" - 8u' - 6.5u - -4 sin(3t), u(1) = -5, u'(1) = -3.5 Use v to represent the "velocity function", i.e. v = u'(t). Use u and v for the two functions, rather than u(t) and v(t). (The latter confuses webwork. Functions like sin(t) are OK) Now write the system using matrices: & 1: 1- 188 1 (:1 181 and the initial value for the vector valued function is: Note: You can earn partial credit on this problem.
