(10 points) write the given second order equation as its equivalent system of first order equations u"2.5u-2.5u = -5.5 sin(3t) u'(1)-3.5 u(1) = -5, use u to represent the "velocity function", i. e. v = u'(t). and u for the two functions, rather than u(t) and v(t). (the latter confuses webwork. functions like sin(t) are ok.) use now write the system using matrices: u u dt v and the initial value for the vector valued function is: u(1) v(1)
