Asin Function In Sql in SQL
? ASIN() Function in SQL
The ASIN() function returns the arcsine (inverse sine) of a number. The result is in radians.
? Syntax
ASIN(number)numbermust be between -1 and 1 (inclusive).Returns a float value representing the angle in radians.
? Examples
1. Arcsine of 0.5
SELECT ASIN(0.5);-- Returns approx 0.523598 (which is ?/6 radians)2. Arcsine of -1
SELECT ASIN(-1);-- Returns -1.570796 (which is -?/2 radians)? Note on Output
Result is in radians.
To convert to degrees, multiply by
(180 / PI()).
SELECT ASIN(0.5) * 180 / PI() AS asin_degrees;-- approx 30 degrees? Use Cases
Trigonometric calculations in data processing.
Geometry or physics-related computations inside SQL.
?? Supported In
MySQL
PostgreSQL
SQL Server (from SQL Server 2012+)
Oracle
If you want, I can also show you other trig functions in SQL like SIN(), COS(), ATAN(), or how to handle degrees vs radians conversions!
