解析几何中定值问题的探究

The Study of Constant Value Problems in Analytical Geometry

通过对解析几何中一类定值问题的探究,给出了此类问题的解题方法:设变量,确定相应的函数,然后由函数是常数函数得到问题的解.有利于提高学生的解题能力,减轻学生的课业负担.

By studying a category of constant value problems in analytical geometry, the paper proposes solutions to the problems： setting the variable, determining the function to get the solution. The study helps students reduce learning burden.
