ASIN
DOUBLE ASIN(DOUBLE X);
Section titled “DOUBLE ASIN(DOUBLE X);”- x: This parameter represents a floating-point value within the range of -1 to 1 inclusive. It’s the value whose arc sine is to be returned.
Example
Section titled “Example”SELECT ASIN(1);Output
Section titled “Output”1.5707963267949Explanation
Section titled “Explanation”In this example, the ASIN() function is used in MySQL to return the arc sine of the number 1. The output, 1.5707963267949, is the radian equivalent of 90 degrees.
ASIN(double precision) —> double precision
Section titled “ASIN(double precision) —> double precision”- name: double precision
Example
Section titled “Example”In SQL, the ASIN function can be used to compute the arcsine of a number. The following is an example using PostgreSQL:
SELECT ASIN(0.5);Output
Section titled “Output”The output from the above code will be:
0.5235987755983Explanation
Section titled “Explanation”In the example provided, the ASIN function returns the arcsine of 0.5. The result is in radians, and in this specific case, the arcsine of 0.5 is approximately 0.5235987755983.
ASIN( float_expression )
Section titled “ASIN( float_expression )”- float_expression: The parameter `float_expression` is a floating point number in the range of -1 to 1. It represents the value for which the arc sine needs to be calculated. This is an expression of type float or of a type that can be implicitly converted to float.
Example
Section titled “Example”SELECT ASIN(0.5) AS ResultOutput
Section titled “Output”Result---------------0.5235987755983Explanation
Section titled “Explanation”The example demonstrates the ASIN function in SQL Server. The ASIN function returns the arcsine, or inverse sine of a number which is between -1 and 1. In this case, the argument for the ASIN function is 0.5. The result is in radians and is approximately 0.52 radians.
ASIN(n NUMBER) RETURN NUMBER;
Section titled “ASIN(n NUMBER) RETURN NUMBER;”- n number: This is the numerical argument passed to the ASIN function. It should be a value within the range of -1 and 1. The function will return an error if the value lies outside of this range. The ASIN function returns the arc sine of ‘n’. The result is in radians and is between -π/2 and π/2.
Example
Section titled “Example”SELECT ASIN(0) FROM dual;Output
Section titled “Output”0Explanation
Section titled “Explanation”The ASIN function in this example returns the arc sine of 0, which is 0. The ASIN function in Oracle SQL takes a number as argument and returns the arc sine of the number. The returned value is in the range from -π/2 to π/2. The DUAL table is a built-in table in Oracle SQL for functions that return exactly one row.
