Analytic Solutions ( dsolve )

Occasionally it is possible to get an analytic (formula) solution. There's no harm in asking, but you may end up staring at nothing for a long time, or Maple may come back with no answer, or an answer that is completely unintelligible. Here too, when we learn specific methods, we will be able to ask Maple to use precisely those methods. The command is complete by replacing the ? by dependent variable ( independent variable), as in the sugar example, something like S(t).

> IVP := MODEL union convert( IC, set );

> SOLN := dsolve( IVP, VAR );
