数学中有许多问题,形式相似,但实质不同.学生在解决此类问题时,由于对题型“面熟”,极易产生思维误区,张冠李戴,造成解题失误.对这类题型如果能注意捉对配组,类比辨析,对提高学生的分析问题和解决问题的能力无疑是很有益的.现就导数中的一些典型问题捕捉三对,予以解析.题组1(1) There are many problems in mathematics, the form is similar, but the essence is different. When students solve this type of problem, due to the “familiar” type of the question type, it is easy to produce misunderstandings, Zhang Guan Li Dai, causing problems in solving questions. If you can pay attention to such questions type Catching and matching groups, analogy and analysis, is undoubtedly beneficial to improve the students’ ability to analyze problems and solve problems. Now we capture three pairs of typical problems in the derivative and analyze them. Question Group 1 (1)
