Abstract:
In this paper, the asymptotic behavior of intermediate points is discussed for the differential mean value theorem of functions of several variables, which brings about more general results such as:
1)when
ξ=
x0+
θh(0 <
θ < 1) then ???19960212???(||
ξ-
x0||)/(||
h||)=(1)/(2).
2)As the moving point
x0+
h tends to
x0 along a certain direction,there are intermediate points
ξ not belonging to the joining line between
x0 and
x0+
h, the
ξ, tends to
x0 along another define direction. In this case,
???19960212???(||
ξ-
x0||)/(||
h||)=(1)/(2) ((
