Oracle ASIN() function

Description

The ASIN() is used to calculate the angle value (in radians) of a specified sine. The function returns a value in the range of -pi/2 to pi/2, expressed in radians and returns an error message when the value of the number is not between the ranges -1 to 1.
The function takes any numeric or nonnumeric data type (can be implicitly converted to a numeric data type) as an argument.
If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise, the function returns the same numeric data type as the argument.

Uses of Oracle ASIN() Function
• Trigonometric Calculations: Determine the angle corresponding to a given sine value.

• Mathematical Modeling: Useful in mathematical models and simulations requiring inverse trigonometric functions.

• Engineering Applications: Applied in various engineering fields for angle calculations in radian measure.

• Data Analysis: Assist in data analysis involving trigonometric transformations and calculations.

• Scientific Research: Employed in scientific research for computations involving trigonometric functions and angles.

Syntax:

`ASIN(N)`

Parameters:

Name Description
N A number whose arch sine value is to be retrieved.

Pictorial Presentation of ASIN() function

Example

The statement below will return an error because the number specified as an argument is exceeding the range which can be accepted.

``````SELECT ASIN(4) FROM dual;
```
```

Here is the result.

```SELECT ASIN(4) FROM dual
*
ERROR at line 1:
ORA-01428: argument '4' is out of range
```

Example: ASIN() function using fractional number

The statement below will return the arc sine value of the number specified as an argument.

``````SELECT ASIN(.4) FROM dual;
```
```

Sample Output:

```  ASIN(.4)
----------
.411516846
```
