Description

函数坐标演示器
技术领域:本实用新型属于数学教学用具技术领域,具体地讲是一种函数坐标演示器。
背景技术:目前,在数学教学过程中进行函数讲解时,教师需要在黑板上多次作十字坐标,并描绘抛物线,这样操作起来十分麻烦、费时费力,给教师讲课增加了极大的工作难度。
发明内容:本实用新型的目的是提供一种在数学教学过程中进行函数讲解时操作简便、省时省力的函数坐标演示器。
本实用新型的技术方案是:包括十字坐标架和软钢丝,其特征是在十字坐标架上设有数个弹力夹。
本实用新型的有益效果是:本实用新型结构简单,在数学教学过程中进行函数讲解时操作简便、省时省力,减轻了教师的工作难度。
附图说明:附图1为本实用新型的结构示意图。
图中1、十字坐标架,2、软钢丝,3、弹力夹。
具体实施方式:包括十字坐标架1和软钢丝2,其特征是在十字坐标架1上设有数个弹力夹3。在数学教学过程中进行函数讲解时,用弹力夹3固定软钢丝2即可。
