| Abstract: | This text directs against "higher mathematics" with radical one of function, two steps that lead issue adopt and ask method calculated to lead to go on to "change yuans of lawing"comparatively simple and convenient to ask, have solved the unfavourable factor that abbreviation, calculation making people perplex in the course of the asking and leading of complicated function are apt to make mistakes basically.Set foot on after the work position offering some help in concrete project application of the practice derivative in the course of practising for student back-end further study. |
