TANH

Calculates the hyperbolic tangent of a specified value, which is the ratio of the hyperbolic sine to the hyperbolic cosine of the number, defined as (\tanh(x) = \frac{\sinh(x)}{\cosh(x)}).

Syntax​

SELECT TANH(value) FROM <multipartIdentifier>;

Arguments​

value
A numeric expression for which the hyperbolic tangent is to be calculated.

Return Value(s)​

Returns the hyperbolic tangent of the specified value.

Examples​

Calculate the hyperbolic tangent of 1​

SELECT TANH(1) AS hyperbolic_tangent_value;

This query returns approximately 0.7616, as the hyperbolic tangent of 1 is about 0.7616.

Calculate the hyperbolic tangent of 0​

SELECT TANH(0) AS hyperbolic_tangent_value;

This query calculates the hyperbolic tangent of 0, resulting in 0, since the hyperbolic tangent of 0 is exactly 0.
