随着导数引入高中教材,函数研究的范围随之扩大,三次函数正式成为高考命题中的新亮点.由于三次函数的导数为二次函数,因此,以三次函数为载体,背景新颖独特,利用导数解决的问题在高考中屡见不鲜.但统计显示考生在这方面的得分偏低,解决问题的能力有待进一步加强.下面从高考试题说说导数在三次函数中的应用,供同学们参考. With the introduction of derivative into high school teaching material, the scope of function research expands, and the cubic function becomes the new bright spot in college entrance examination proposition.As the derivative of the cubic function is a quadratic function, taking the cubic function as the carrier, the background is novel and unique, The problems solved in the college entrance examination are common.However, the statistics show that the candidates in this area is low, the ability to solve the problem needs to be further strengthened.The following article from the entrance examination to talk about the derivative function in the third, for the students reference.
