Abstract

The utility model discloses a special-purpose function limit demonstration teaching aid for advanced mathematics, which relates to a teaching appliance, and comprises a bottom plate and a coordinate axis, wherein the coordinate axis is arranged on the bottom plate, the bottom plate is uniformly distributed with crisscrossed straight lines to form a grid, jacks are arranged on cross points of the crisscrossed straight lines, lines are run through on more than two fixed pins, and the fixed pins are inserted in the jacks. The special-purpose function limit demonstration teaching aid for the advanced mathematics is simple in structure, easy to operate and intuitive to express, can change function graphs at any time, saves time of teachers for painting function limit graphs, and is strong in practicability.

Description

A kind of limit of function demonstration teaching aid of higher mathematics special use
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of limit of function demonstration teaching aid of higher mathematics special use.
Background technology
High number is important subject in the university, it is the rudimentary knowledge of other specialized courses of study, also often be utilized in daily life, higher mathematics is primarily aimed at the research of function, relate to limit field, therefore limit of function just seems very important in higher mathematics, the limit is a more abstract thing, usually all express with figure, simple language teaching can not be understood by the student and accept, can in teaching, express the instrument of limit of function at present seldom, majority is that teacher's one by one picture on drawing board is expressed, each a lot of different limiting figures that all need to draw are given lessons, the most hours of instruction that take, and the while has also increased teacher's workload.
Summary of the invention
The utility model is intended at the deficiency that exists in the background technology, and the limit of function demonstration teaching aid of a kind of higher mathematics special use that proposes.
The limit of function demonstration teaching aid of a kind of higher mathematics special use of the present utility model, be to be constituted by base plate and coordinate axis, be provided with coordinate axis at base plate, uniform crisscross straight line constitutes grid on base plate, intersection point at crisscross straight line is provided with jack, is no less than interting lines and being plugged on the jack on two the Fixed latches.
As further improvement of the utility model, the top of Fixed latches is provided with the fixedly groove of lines.
As further improvement of the utility model, be provided with more than one link at the base plate top.
The limit of function demonstration teaching aid of a kind of higher mathematics special use of the present utility model, simple in structure, processing ease is expressed intuitively, and variation functional digraph that can be has at any time been saved the teacher and given a lesson time of picture limit of function figure, and is practical.
Description of drawings
Fig. 1 is structural plan of the present utility model synoptic diagram;
Fig. 2 is partial enlarged drawing of the present utility model and Fixed latches enlarged drawing.
Embodiment
Limit of function demonstration teaching aid below in conjunction with accompanying drawing 1 and 2 pairs of a kind of higher mathematics special uses of the present utility model of accompanying drawing is described further:
The limit of function demonstration teaching aid of a kind of higher mathematics special use of the present utility model, be to be constituted by base plate 1 and coordinate axis 2, be provided with coordinate axis 2 at base plate 1, uniform crisscross straight line constitutes grid 3 on base plate 1, intersection point at crisscross straight line is provided with jack 4, is no less than interting lines 6 and being plugged on the jack 4 on two the Fixed latches 5.Described Fixed latches 5 is to be provided with the fixedly groove 7 of lines 6 at its top.Base plate 1 top is provided with more than one link 8, the convenient suspension.
