Similarly, to define a PDE object we use the fact that one needs only to define the coefficients of the PDE and solve the PDE. The PDE object has advanced features, but these are not required in simple cases.

 never use and do not need to understand. Similarly, to define a PDE object we use the fact that one needs only to define the coefficients of the PDE and solve the PDE. At a later stage you may use more advanced features of the PDE class, but you need to worry about them only at the point when you use them.
