hello
I use
plots[odeplots](dsol,[t,(D(X[5](t))(t),0..5,numpoints=100);
when dsol=dsolve(..........) which is a procedure to plot first derivative of X[5] now I wanna know what should I use to plot second derivative of that
I used
plots[odeplots](dsol,[t,(D[1,1](X[5](t))(t),0..5,numpoints=100); but nothing shows up
and some other commands none of them works for me.
Thanks
bye
