解答数学问题实际上是一个转化的过程,转化的原则是等价转化.如果在转化过程中,对题目进行了非等价转化的话,就常会导致问题解的缩小或扩大,这是一种同学们经常易犯的逻辑错误,解题中稍有疏忽,就会掉入题目设置的陷阱中。这种逻辑陷阱分为两类: Solving the mathematics problem is actually a transformation process, and the principle of transformation is the equivalent transformation. If the subject is transformed non-equivalently in the transformation process, it will often lead to the reduction or expansion of the problem solution. This is a classmate. They are often apt to make logical mistakes. If there is a slight oversight in the problem, they will fall into the trap of the topic setting. This logical trap falls into two categories:
