一种数学曲线专用演示装置
本技术属于教学辅助装置
,尤其涉及一种数学曲线专用演示装置。
技术介绍
目前,业内常用的现有技术是这样的,在高等数学教学的过程中,经常涉及到复杂的曲线,曲线绕旋转轴旋转就能形成曲面,对于复杂的曲线和曲面,很难直观的看出曲面与曲线之间的联系。为了能够在课堂上使学生尽快理解复杂曲线和曲面的关系,需要授课老师能够较形象的绘画出曲线图,但是一些曲线不易绘画,授课老师需要建立相关的坐标系并且取相关的坐标点才能绘画出曲线,这就浪费了课堂的时间,影响授课的进度。综上所述,现有技术存在的问题是:对于不易绘画的曲线或者曲面,授课老师需要建立相关的坐标系并且取相关的坐标点才能绘画出曲线,浪费了课堂的时间,影响授课的进度。
