输入余割值,计算对应的角度和弧度。
反余割函数(Arccosecant function)是余割函数的反函数,通常用符号 \(\operatorname{arccsc}(x)\) 或 \(\csc^{-1}(x)\) 表示,用于计算给定余割值对应的角度。对于余割函数 \(y = \csc(\theta)\),反余割函数定义为: \( \theta = \operatorname{arccsc}(x) \) 其中,\(x \leq -1\) 或 \(x \geq 1\),而角度 \(\theta\) 的值域为 \([- \frac{\pi}{2}, \frac{\pi}{2}]\) 且 \(\theta \neq 0\)。这样定义使得反余割函数唯一且可逆。
解答:
\( \theta = \operatorname{arccsc}(2) \approx 0.523 \, \text{弧度} \)
因此,余割值为 2 的角度约为 0.523 弧度或 30°。
解答:
\( \theta = \operatorname{arccsc}(-2) \approx -0.523 \, \text{弧度} \)
所以,余割值为 -2 的角度约为 -0.523 弧度或 -30°。
反余割函数的图形包括在定义域内的两段曲线,范围从 \((-\infty, -1] \cup [1, +\infty)\),其值域为 \([- \frac{\pi}{2}, \frac{\pi}{2}]\)(不包含 0)。图形的主要特性包括:
