Consider the differential equation,$y''+2y=cos(kt)$, what is the values of k such that solutions to the differential equation are unbounded

    So many questions asked and you still do not know that one is supposed to show what one tried, why this failed, and so on?2012-05-07

    WolframAlpha can solve the differential equation for you. All that remains is to check for which values of $k$ this is unbounded.2012-05-07
