| Abstract: | In this paper,the methods of coordinate transformation,analysis expression and geometry meaning were put to use in order to grant Lagrange's theorem to prove the processes of thinking and methods of several auxiliary functions.And how to apply the Lagrange's theorem to practice was discussed with some examples. |
