本文是笔者经过几年的高三教学经验和心得,在教学实践中总结出来的。是学生在学习或是复习三角函数图像与性质时,利用其图像和性质解题时的常见错误。本文主要从三个方面举例来说明学生解题时常见错误:⑴、抓不住图像平移实质而产生的错误。⑵、三角函数性质滥用而产生的错误。⑶、审题不清而产生错误。
This article is the author's experience and experience in senior high school teaching after several years, summed up in the teaching practice. It is a common mistake when students are learning or reviewing the image and nature of trigonometric functions by using their image and nature to solve problems. This article mainly from three aspects of examples to illustrate the common mistakes when students solve problems: (1), can not grasp the essence of the image translation error. (2) Misuse of trigonometric functions. (3) An error occurred when the question was unclear.
