解答数学题的基本思路,是通过由因导果或执果溯因。确立题中条件与结论或条件与问题在逻辑上的必然联系,实现由已知向未知的转化。结构灵活、抽象多变的数学题实现上述转化的关键,常常是发掘并利用题中的隐含条件。 所谓隐含条件,是指题中若明若暗、含蓄不露的已知条件,它们常是巧妙地隐蔽在题设的背后,不易 The basic idea of ​​solving a mathematics problem is to trace the cause by the result of directing fruit or fruit. Establish logically necessary connections between conditions and conclusions or conditions in the question and the realization of the transformation from known to unknown. The key to achieving the above transformation is to solve the problem of the structurally flexible and abstract mathematics problem. It is often to explore and use the implicit conditions in the problem. The so-called implied conditions are the known conditions of darkness and implicitness. They are often concealed behind the title and are not easy to conceal.
