这是笔者的一节校级公开课,是在高三复习完三角函数的图像和性质后,从平时学生所做的习题中得到启发,基于熟知的不等式x>sinx的一节探究课.现将课堂教学过程整理如下,与大家交流.笔者一开始请一学生在黑板上同一坐标系中画出函数y=sinx(x∈
This is a section of the author’s school open class, is in the high school after reviewing the image and the nature of the trigonometric function, inspired by the usual students to do exercises, based on the well-known inequality x> sinx an inquiry class. Classroom teaching process is organized as follows, to communicate with you.I start with a student on the blackboard in the same coordinate system draw function y = sinx (x ∈
