I’ve written several posts about applying trig functions to inverse trig functions. I intended to write two posts, one about the three basic trig functions and one about their hyperbolic counterparts. But there’s more to explore here than I thought at first. For example, the mistakes that I made in the first post lead to a couple more posts discussing error detection and proofs. I was curious about how Mathematica would handle these identities. Sometimes it doesn’t simplify expressions the wa…

我已经写了几篇关于将三角函数应用于反三角函数的文章。我打算写两个帖子，一个是关于三个基本的TRIG函数，一个是关于它们的双曲线对应函数。但是这里有比我最初想象的更多的东西可以探索。例如，我在第一篇帖子中犯的错误导致更多帖子讨论错误检测和证明。我很好奇Mathematica将如何处理这些身份。S 有时它并不能简化表达式，
