This paper discusses and summarizes the problem solving in analytic geometry parameter equation application, mainly introduced how to use to reduce the analytic geometry parameter equation of difficulty of the questions.
Firstly illustrates the basic definition parameter equation, understand what is the parameter equation.
Secondly focus on specific reasoning and problem solving, from linear parameter equation, secondary curvilinear parameter equation, let the parameter equation trajectory respectively to behave the three aspects in analytic geometry parameter equation problem solving, thus make use of more specific parameter equation of use.
Finally summarized the appropriate use of questions and the parameter equation problem solving characteristic. Believe in after reading this reader to in analytic geometry parameter equation application have more specific knowledge.
