Abstract: Based on the distinguishing theorem for convex function,the author  indicates some problems needing attention on proving inequation by using convex function:whether there exists second derivative is the starting point in proving some inequation.The author then proves the matrix form of Kantorovich inequation by using the property of convex function.

Key words: convex function, inequation, Kantorovich inequation
