Below is the example of the Math asin( ) Method.
document.write("When 1 is passed as a parameter: "
When 1 is passed as a parameter: 1.5707963267948966
The Math.asin( ) method is used to return the arcsine of a number in radians. The Math.asin() method returns a numeric value between -pi/2 and pi/2 radians. The asin() is a static method of Math, therefore, it is always used as Math.asin(), rather than as a method of a Math object created.
where y belongs to [-pi/2;pi/2]
such that sin(y)=x
Parameters: This method accepts a single parameter as mentioned above and described below:
- value: This parameter holds a number in radians who arcsine you want to find.
Returns: The Math.asin() method returns the arcsine of the given number in radians.
- Example 1:
Input : Math.asin(1) Output : 1.5707963267948966
- Example 2:
Input : Math.asin(-1) Output : -1.5707963267948966
- Example 3:
Input : Math.asin(2) Output : NaN
- Example 4:
Input : Math.asin(0.5) Output : 0.5235987755982989
More example codes for the above method are as follows:
When -1 is passed as a parameter: -1.5707963267948966
When 2 is passed as a parameter: NaN
When 0.5 is passed as a parameter: 0.5235987755982989
