函数单调性是函数的一个重要性质,在研究函数时有着非常广泛的应用,可以使得数学当中的许多问题求解起来更为简单明快,本文在了解函数单调性的定义及判别方法上,对函数单调性在解题中的有关应用进行了一系列探析。当然,课堂教学最为关键的就是让学生知道函数单调性是函数的重要性质之一,并且为他们创设一定的情境,让他们进行合作讨论,并进行尝试、体验、猜测,在解决函数单调性问题的过程中形成一定的自主创新能力,使学生真正“会学”。 Function monotonicity is an important property of the function. It has a very wide range of applications in the study of functions, which can make many problems in mathematics easier to be solved. On the understanding of monotonicity of function definition and discrimination method, Sex in the problem-solving applications for a series of analysis. Of course, the most crucial point of classroom teaching is to let students know that monotonic function is one of the important properties of the function, and create a certain situation for them, let them cooperate to discuss, and try, experience, guess, in solving the monotonic function In the process of forming a certain degree of independent innovation ability, so that students truly “learn ”.
