ithout solving it, rewrite the given second order differential equation t'u" - 3.5tu' + (t² − 1)u = −7 sin(3t) an equivalent system of first order differential equations. In your answer use the single letter nd the single letter v to represent the "velocity function" u'. Do not u(t) or v(t) to represent the n(t) that represent other functions are OK.
