An online calculator to calculate inverse cosecant function arccsc(x) in radians and degrees. The graph of y = arccsc(x) is shown below and it has the horizontal asymptote \( y = 0 \) defined as
\( \lim_{x\to-\infty} arccsc(x) = 0 \) and \( \lim_{x\to 0} arccsc(x) = 0 \)
The domain of y = arccsc(x) is given by: \( -\infty \lt x \le -1 \quad \cup \quad 1 \le x \lt \infty \)
The range of y = arccsc(x) is given by: \( - \dfrac{\pi}{2} \le y \lt 0 \quad \cup \quad 0 \lt y \le \dfrac{\pi}{2} \)

How to use the arccsc (x) calculator

1 - Enter x as a real number and the number of decimal places desired then press "enter". Two answers; one in radians and the other in degrees are displayed. For any value of x outside the domain defined above "NaN"(not a number) is displayed.

You may use it to explore the domain and range of arccot(x).
