| Abstract: | Seeking the maximum and minimum of function is the perpetual topic in the medium-sized mathematics,and the function of many variables are difficulties. We usually use the following common methods： elimination method, means of inequality,the method of element changing, the methods of integrating algebra with geometrical figure, the method of cauchy inequality and the method of vectors etc. With examples the author illustrates these methods. |
