问题已知锐角α、β满足1,求证;α+β=π/2. 这是常见于大多数竞赛书中的一道三角题,由于其含有一定的逆向思维,故对一般的同学而言是有一定难度的.实际上,由已知中的平方形式可联想到配方法,也可由已知式的 The problem is known as the acute angle α, β satisfies 1, confirming; α + β = π/2. This is a trigonometric question that is common in most competition books. Because it contains a certain amount of reverse thinking, it is for the general classmates. There is a certain degree of difficulty. Actually, the known squared form can be associated with the matching method, and it can also be known by
