高一数学第一章是集合的有关知识,这无论是对以后各章的学习,还是提高学好数学的信心都是致关重要的.一般地,解决集合的有关问题需要注意以下两个要点.一、弄清集合的本质是什么解决集合的问题首先得搞清楚有关集合的本质,具体点说就是集合中元素的本质是什么.如果在学习中不注 The first chapter of mathematics in senior mathematics is related to the collection of knowledge. Whether it is learning in the following chapters or improving the confidence in learning mathematics is important. In general, the following two points need to be paid attention to in solving problems related to sets. First, understand the nature of the collection is to solve the problem of the collection First of all have to figure out the essence of the collection, the specific point is that the essence of the elements in the collection is. If not in the study
