Arccsc(x) Calculator — inverse cosecant function

How to use the arccsc(x) calculator
1. Enter a real number \(x\) such that \(|x| \ge 1\) and choose decimal places.
2. Press calculate arccsc(x). The answer is displayed in radians and degrees.
If x is outside the domain (\(-1 < x < 1\)), "NaN" is displayed.

Formulas used:
\[ \text{arccsc}(x) = \arcsin\left(\frac{1}{x}\right) \quad \text{(principal value range: } [-\pi/2,0) \cup (0,\pi/2] \text{)} \]
\[ \text{degrees} = \text{radians} \times \frac{180}{\pi} \]

• Domain: \( (-\infty, -1] \cup [1, \infty) \) (|x| ≥ 1)
• Range: \( [-\pi/2 , 0) \cup (0 , \pi/2] \) radians (\(-90^\circ\) to \(90^\circ\), excluding 0°)
