解析几何是在坐标系的基础上,用代数方法研究几何图形性质的一门数学学科.因此,代数运算就不可避免地出现在解析几何问题中.在解决某些解析几何问题时,如果方法选择不当,往往会导致计算繁琐,不仅会浪费宝贵的时间,而且还不易得到正确的结果.那么如何恰当地选择方法,减少运算量?
Analytic geometry is a mathematical discipline that uses algebraic methods to study the nature of geometrical figures on the basis of coordinate systems. Therefore, algebraic operations inevitably occur in analytical geometry problems. When solving certain analytical geometric problems, if the method is chosen Inappropriately, it will often lead to complicated calculations. It will not only waste precious time, but it will not be easy to get correct results. How to properly select methods and reduce the amount of calculations?
