You must supply this method to calculate the values of Fx and
dF
dx
at any point x in a,b.
It should be tested separately before being used in conjunction with
e04bb.

Parameters
- xc
- Type: System..::.Double
On entry: the point x at which the values of F and
dF
dx
are required.

System..::.Double
%
On exit: must be set to the value of the function F at the current point x.
- gc
- Type:
System..::.Double
%
On exit: must be set to the value of the first derivative
