In this section we discuss Axiom's facilities for solving differential
equations in closed-form and in series.
Axiom provides facilities for closed-form solution of single differential
equations of the following kinds:
<ul>
<li>linear ordinary differential equations
</li>
<li>non-linear first order ordinary differential equations when integrating
factors can be found just by integration
</li>
</ul>
For a discussion of the solution of systems of linear and polynomial
equations, see <a href="axbook/section-8.5.xhtml">Solution of Linear
and Polynomial Equations</a>.
