ASINH

Description

The ASINH function is used to calculate the inverse hyperbolic sine of a given numeric expression. The inverse hyperbolic sine function is the inverse of the hyperbolic sine function, and its result will return a hyperbolic sine value related to the input value.

Syntax

ASINH(expr)

Parameters

• expr: The numerical expression for which the inverse hyperbolic sine value needs to be calculated, of type DOUBLE.

Return Value

Returns the inverse hyperbolic sine value related to the input expression, of type DOUBLE.

Example Usage

1. Calculate the inverse hyperbolic sine value of 0:

SELECT ASINH(0);
-- Result: 0.0

In this example, the input value is 0, and its inverse hyperbolic sine value is also 0.

2. Calculate the inverse hyperbolic sine value of -1:

SELECT ASINH(-1);
-- Result: -0.8813735870195429

In this example, the input value is -1, and its inverse hyperbolic sine value is approximately -0.8814.

3. Calculate the inverse hyperbolic sine value of a positive and a negative number:

SELECT ASINH(2), ASINH(-2);
-- Result: 1.4436354751788103, -1.4436354751788103

In this example, we calculate the inverse hyperbolic sine of the positive number 2 and the negative number -2, resulting in 1.4431 and -1.4431, respectively.

4. Calculate the inverse hyperbolic sine of a smaller negative number and a larger positive number:

SELECT ASINH(-0.1), ASINH(3);
-- Result: -0.09983407889920758, 1.8184464592320668

In this example, we calculated the inverse hyperbolic sine values of the smaller negative number -0.1 and the larger positive number 3, resulting in -0.1001 and 1.8831, respectively.

From the above example, you can see that the ASINH function can handle inputs of different positive and negative values and return the corresponding inverse hyperbolic sine values. This makes the ASINH function very useful in mathematical calculations and data analysis.
