一、抓住基础,厘清概念在很多同学的心里,定义或许是高中数学学习中最易被忽略但也是最不容忽视的部分了.我们所接触到的数学定义,都是经过千锤百炼而成的,其中许多细节都饱含深意,能够用来帮助我们解决问题.例如,二次函数定义中明确指出的二次项系数不为零这一细节,常常在解题时被同学们遗漏,而出现讨论不充分的情况.同样,对定义的熟悉能很好地帮助同学 First, to seize the foundation, to clarify the concept In the hearts of many students, the definition may be the most easily overlooked but also the most overlooked part of high school mathematics learning the mathematical definitions we have come into contact, are made through tempered, Many of these details are profound and can be used to help us solve the problem.For example, the detail of the quadratic function that the non-zero coefficient of the quadratic coefficient is often omitted by the students when the problem is solved, In the same way, familiarity with definitions can be good for students
