Calculate the inverse sine value using the javascriptasin Method

The javascriptasin method returns the arc sine of a number. If the calculated value exceeds the range of-1.0 to 1.0 or calculates the inverse sine of a non-numeric value, NaN is returned. This article describes how to use the asin function through examples. For more information about the coders, see. The asin method returns the arc sine of a number.

Basic syntax

Math.asin(number)

The required number parameter is a numeric expression that needs to calculate the arcsin.

Return Value

The return value is the arc sine of the numeric parameter (The radian value between-PI/2 and PI/2 ).

Notes:

1. If the value of x exceeds-1.0 ~ In the range of 1.0, the browser returns NaN.
2. If the parameter is not a number, NaN is returned.
3. If the value of x is 1, PI/2 is returned.
