近几年的全国高考试题和各地模拟试题,常常涉及到一元三次函数.这类试题能较好地考查学生潜能且与新教材内容有联系,下面笔者对一元三次函数常用求解策略作一归纳,供同学们学习参考. 一、降次转化例1 (1998年高考题)设曲线C的方程是y=x3-x,将C沿 In recent years, the national examination questions and simulation questions in various places often involve a one-dimensional three-time function. Such questions can better examine the students’ potential and are related to the contents of the new teaching materials. The following section summarizes the commonly used solution strategies of the one-dimensional cubic function. For students to learn reference. First, descending conversion example 1 (1998 college entrance examination questions) set the equation of curve C is y = x3-x, the edge of C
