ASIN

ASIN(number)

Returns the angle in radians for a given sine ratio.

number

The sine ratio.

REMARKS

* For an illustrated example refer to the Trigonometric Functions page.
* This function always returns an angle between -PI/2 and PI/2.
* If "number" is not numeric, then #VALUE! is returned.
* If "number" > 1, then #NUM! is returned.
* If "number" < -1, then #NUM! is returned.
* To convert a number from degress to radians, multiply it by PI/180.
* To convert a number from radians to degrees, multiply it by 180/PI.
* The inverse of this function is the SIN function.
* You can use the SIN function to return the sine of a number.
* You can use the ACOS function to return the arc-cosine.
* You can use the ACOT function to return the the arc-cotangent.
* You can use the ATAN function to return the arc-tangent.
* You can use the RADIANS function to convert from degrees to radians.
* You can use the DEGREES function to convert from radians to degrees or multiply it by 180/PI.
* For the Microsoft documentation refer to support.microsoft.com
