Why didn’t Sinh[ ArcCosh[x] ] just return √(x² − 1)? The expression it returned is equivalent to this: just square the (x + 1) term, bring it inside the radical, and simplify. That line of reasoning is correct for some values of x but not for others. For example, Sinh[ArcCosh[2]] returns −√3 but √(2² − 1) = √3. The expression Mathematica returns for Sinh[ArcCosh[x]] correctly evaluates to −√3.
当前，AI算力需求正以超越摩尔定律的速度指数级增长。OpenAI的研究显示，自2012年以来，前沿AI训练任务所需的算力每3.4个月翻一番，累计增长超过30万倍。大模型从千亿参数向万亿参数迈进，端侧智能从简单感知向复杂决策演进，算力成为新一代AI竞赛的核心壁垒。
