Numerical Solutions
===================

Not all equations can be solved symbolically.  The commands in this
section use numerical algorithms that can find a solution to a
specific instance of an equation to any desired accuracy.  Note that
the numerical commands are slower than their algebraic cousins; it is
a good idea to try `a S' before resorting to these commands.

(See Curve Fitting, for some other, more specialized, operations
on numerical data.)
