在高中解析几何中我们常常会涉及到两曲线相交的有关问题.对于此类问题,利用曲线系方程巧妙地解题往往被师生所忽视,从而导致一些试题在解题过程中出现繁杂的运算,甚至思维受阻,无功而返.如果能熟练掌握曲线系方程,并在相关问题中加以灵活运用,那么解题过程一定会更加流畅,解题效率也必将会大大提高.下面列举几例,阐述曲线系方程的奇思与妙用,供读者参考. In high school analytic geometry we often relate to the problem of intersection of two curves.For such problems, the use of curve equation cleverly solve the problem is often overlooked by teachers and students, resulting in a number of questions in the process of solving complex problems , And even blocked thinking, without success .If you master the curve equation, and in the relevant issues to be flexible use, then the problem-solving process will be more fluid, problem-solving efficiency will also be greatly enhanced. , Explain the curiosity and magical curve equation, for the reader’s reference.
