数学等式的求解或证明是数学的重要元素,而数学中的不等式问题的求解或证明也是数学学习中的不可或缺的一部分.“等”与“不等”是两个不同的概念,“不等”是普遍的、绝对的,而“相等”是局部的、相对的,两者既对立又统一,它们在一定条件下可以相互和谐转化,从而使得问题理想而巧妙地得到解决.转化得好可以给解题带来意想不到的效果,下面就两者的相互转化略举几例,供大家分享!例1已知α,β∈(0,π2),且sin(α+β)= Solving or proving mathematical equations is an important element of mathematics, and solving or proving inequalities in mathematics is also an integral part of mathematical learning. “” “Equal” and “unequal” are two different The concept of “unequal ” is universal and absolute, and “equal ” is partial and relative, both of them are antithetical and uniformed. Under certain conditions, they can be harmoniously transformed with each other so that the problem is ideal And cleverly be solved. Transformation is good can bring unexpected effects, the following conversion between the two a few, for you to share! Example 1 known α, β ∈ (0, π2), and sin (α + β) =
