Inverse Sine (arcsin)

The inverse sine function, also known as arcsin, is the inverse operation of the sine function. It takes a number (x), which is the sine of an angle, and returns the angle in radians whose sine is x. The domain of arcsin is 1 ≤ x ≤ 1, and the range is π/2 ≤ y ≤ π/2, where y is the output angle in radians. It is important to know that the JavaScript Math.asin() function returns the angle in radians, and to convert it to degrees, you would use the calculation (Math.asin(x) * 180) / Math.PI.
