Arcsin(x) Calculator — inverse sine function

How to use the arcsin(x) calculator
1. Enter a real number \(x\) in the domain \([-1 , 1]\) and choose the number of decimal places.
2. Press calculate arcsin(x). The answer is displayed in radians and degrees.
If x is outside the domain (\(x < -1\) or \(x > 1\)), the output shows "x out of domain".

Formulas used:
\[ \text{arcsin}(x) = y, \quad \sin(y) = x,\quad y \in [-\pi/2,\pi/2] \]
\[ \text{degrees} = \text{radians} \times \frac{180}{\pi} \]

• Domain: \(-1 \le x \le 1\)
• Range: \(-\pi/2 \le \text{arcsin}(x) \le \pi/2\) radians   ( \(-90^\circ\) to \(90^\circ\) )

Example: \(\arcsin(0) = 0\) rad ( \(0^\circ\) ), \(\arcsin(1) = \pi/2 \approx 1.571\) rad ( \(90^\circ\) )
