Abstract

The invention discloses a mathematical function forming system, and relates to the field of mathematical teaching equipment, especially a mathematical function forming system. The mathematical function forming system comprises a pedestal plate, a painting paper rotating device, a longitudinal movement apparatus, a guide bar, a paintbrush, a controller and a computer, wherein the front and back ends of the pedestal plate are respectively provided with an arc groove; two sides of each arc groove are provided with a baffle plate; a driving roller is arranged in the arc groove in the back end of the pedestal plate; a driven roller is arranged in the arc groove in the front end of the pedestal plate; a roller motor is fixed at the outside of the pedestal plate; an driven roller shaft is arranged in an inner hole of the driven roller; the painting paper is wound around the driven roller; the tail end of the painting paper is connected with the driving roller through the upper surface of the pedestal plate; the guide bar is horizontally arranged at the middle part of the pedestal plate; and the longitudinal movement apparatus is arranged on the guide bar. The mathematical function forming system solves the problems that during a current geometrical teaching process, a geometrical curve cannot be drawn visually and the drawn geometrical curve is not standard.

Description

technical field [0001] The invention relates to the field of mathematics teaching equipment, in particular to a mathematical function forming system. Background technique [0002] In mathematics, a function is a relation such that every element in one set corresponds to a unique element in another set. In the teaching of mathematical functions, general teachers use theoretical teaching. Chinese patent document CN103192633A discloses a trigonometric function curve plotter. This patent can draw sine curves and cosine curves, and can obtain curves of different periods; the amplitude of any size can be adjusted. In the process of geometry teaching in this patent, geometric curves cannot be intuitively drawn, and the drawn geometric curves are not standard. Contents of the invention [0003] The invention provides a mathematical function forming system, which solves the problems that geometric curves cannot be intuitively drawn and the drawn geometric curves are not standard i...
