| Abstract: | This paper analyses the definition,stable point and the sufficient conditions of taking the extreme value of monadic function by using counter-examples,gives the discriminant method of taking the extreme value of nonconductable point,discusses the problem of the existence and uniqueness of the extremum point of function and makes clear the relations between extreme value and maximum value,minimum value,extremum point and break point. |

| Keywords: | extreme value stable point maximum value and minimum value break point |
