ASIN function in Oracle

ASIN is one of the vital Numeric/Math functions of Oracle. It is used to get the arc sine of a number. The ASIN function is supported in the various versions of the Oracle/PLSQL, including, Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i and Oracle 8i.

Syntax:

ASIN ( number )

Parameters:
number: It is used to specify the number to get the arc sine value of.

Example 1:

ASIN (1)

Output:

1.57079633

Explanation:
The Arc sine means the inverse of the sine. The arc sine value of 1 is 90 degrees i.e, 1.57079633 radians, and so is the result.

Example 2:

ASIN (0.5)

Output:

0.52359878

Explanation:
The Arc sine means the inverse of the sine. The arc sine value of 0.5 is 30 degrees i.e, 0.52359878 radians, and so is the result.

Example 3:

ASIN (-0.5)

Output:

-0.52359878

Explanation:
The Arc sine means the inverse of the sine. The arc sine value of -0.5 is -30 degrees i.e, -0.52359878 radians, and so is the result.
