解析几何是用代数的方法来研究几何问题的一门学科,不等式是代数中的一个重要内容,圆锥曲线中的范围问题将二者有效地结合起来了,因此,它成为各级各类考试中命题的热点.圆锥曲线中二元范围问题就是问题中含有两个变量或者在解决问题过程中必须引进第二个变量的范围问题.这类问
Analytic geometry is a discipline that uses algebraic methods to study geometric problems. Inequality is an important part of algebra. The scope problem in the conic section combines the two effectively. Therefore, it becomes an examination of various types of examinations. Propositional hotspots. The binary range problem in conic curves is the problem of having two variables in the problem or the scope of the second variable that must be introduced in the problem solving process.
