Arctan和tan-1一样吗
Web反正切函數是y = tan（x）的反函數。 arctan ... 例如，如果45°的切線為1： tan（45°）= 1. 那麼1的反正切為45°： arctan（1）= tan -1 （1）= 45 ... 該網站使用Cookie來改善您的 … WebJan 11, 2024 · $\begingroup$ (+1) One other reason I dislike the $\tan^{-1}$ notation is because it suggests that the $\tan$ function has an inverse. This is not true: $\tan^{-1}(\tan(x)) \neq x$ in general. People often say '$\tan$ has an inverse on a restricted domain', but when you restrict the domain of a function, you are creating a new one.
