asin[]

Returns the arc sine of number, expressed in degrees.

The asin[] function is a function that returns the arc sine of a number. The arc sine, or inverse sine, of a number is the angle (in degrees) whose sine is equal to the given number. The input to the function should be a value between -1 and 1, and the output will be in the range of -90 to 90 (degrees). For example, asin[1] would return 90 and asin[0] would return 0.

Syntax

asin[x]

Parameters

x Number whose arc sine is computed, in the interval [-1,+1].
Return Value Principal arc sine of x, in the interval [-90,90] degrees.
If the argument is out of interval, return value is NaN.

Examples

#<result> = asin[1]
(print,#<result>)

result: 90 

#<result> = asin[0]
(print,#<result>)

result: 0
