通过教学我发现我们大多数人对曲线的切线认识的还不够全面,甚至还有一些错误的观点。本文就曲线的切线给予简短的归纳和总结。一、对圆的切线的认识首先,学生对于切线的认识,是一个循序渐进的过程。从初中到高中,大致分为三个阶段。第一阶段是在初中从圆的切线开始的。由于当时对切线只是一种直观的认识,学习了圆的切线后,很多学生认为,所谓曲线的切线,就 Through teaching I found that most of us know the tangential curve is not comprehensive enough, and there are even some wrong ideas. This article gives a brief summary and summary of the tangent of the curve. First, the understanding of the tangent of the circle First, the students understanding of the tangent is a gradual process. From junior high school to high school, roughly divided into three stages. The first stage starts with a tangent to the circle in junior high school. Because at the time of the tangent is only an intuitive understanding of the circle tangent learning, many students think that the so-called tangent curve
