        * The arc length of the graph of f from A(a,f(a)) to B(b,f(b))

        c05d1A.c  : f : x->   x + 1
        c05d1B.c  : f : x->   x**2
        c05d1C.c  : f : x->   sin(x)
        c05d1D.c  : f : x->   log(x)
        c05d1E.c  : f : x->   exp(x)
 

        * The area S of the surface generated by revolving 
          the graph of f about the x-axis is (ONLY A GIFT GRAPH).
