strange behavior or bug on ode2



You have not done anything wrong----maxima gets stuck trying to 
integrate 

      integrate(exp(t/2) *sin(t) * sin(sqrt(3) * t/2),t);

Doing gcd == spmod or algebraic == true doesn't help.
This is a bug.  If you could, please report it to our
buglist at

       http://sourceforge.net/tracker/?group_id=4933&atid=104933

Thanks for the report.

Hello,

I found that Maxima has trouble solving some very simple ode's, e.g.,

(%i1) ode2('diff(y,t,2)+'diff(y,t)+y-sin(t),y,t);
