集合是高中数学的起始课,同时也是学习后续知识的基础.学生初次接触它,不免会产生各种各样的错误,笔者现将这些常见的错误归纳出来,并进行简要的剖析,希望会对大家有所启发.1.错误一:随意书写.例1请将下列集合用描述法表示出来.(1){1,4,7,10};(2){(1,4),(7,10)}.错解(1){x=3k+1 The collection is the initial class of high school mathematics, but also the basis for learning the follow-up knowledge.Students first contact with it, inevitably will produce a variety of errors, the author is now summarized these common mistakes, and a brief analysis, I hope For everyone to inspire .1 error: free to write .Example 1 Please use the following collection expressed by the method of (1) {1,4,7,10}; (2) {(1,4), ( 7,10)}. The wrong solution (1) {x = 3k +1
