number (number)

The number to calculate the arcsine of (must be between -1 and 1)

number

The arcsine in radians

Input:

1 | asin

Output:

1.571... (π/2)

Input:

asin(0)

Output:

Input:

asin(0.5)

Output:

0.524... (π/6)

The asin() function calculates the inverse sine (arcsine) of a number, returning the result in radians.

Use asin() to find angles from sine values in trigonometric calculations. Input must be between -1 and 1.
