| Abstract: | In order to reduce the difficulty of learning composite motion of point in theoretical mechanics, this paper carries out exploration and practice. Based on related concepts and theorems of higher mathematics, this paper analyzes speed synthesis theorem and acceleration synthesis theorem of composite motion of points using methods of limit and derivative, puts forward the concept of implicated derivative, and tests the applicability of the methods in teaching practice. |
