TAN

Description

The TAN function is used to calculate the tangent of a given angle. In mathematics, the tangent value represents the ratio of the opposite side to the adjacent side in a right-angled triangle. This function has a wide range of applications in trigonometric calculations and angle conversions.

Syntax

TAN(expr)

Parameters

• expr: The angle for which the tangent value needs to be calculated, of type DOUBLE.

Return Value

Returns the calculated tangent value, of type DOUBLE.

Example

1. Calculate the tangent value of 0 degrees:

SELECT TAN(0);
-- Result: 0.0

2. Calculate the tangent value of 45 degrees:

SELECT TAN(45);
-- Result: 1.6197751905438615

3. Calculate the tangent of 90 degrees (result is infinity):

SELECT TAN(90);
-- Result: -1.995200412208242

4. Calculate the tangent of -90 degrees (result is negative infinity):

SELECT TAN(-90);
-- Result: 1.995200412208242

5. Calculate the tangent value of 180 degrees:

SELECT TAN(180);
-- Result: 1.3386902103511544
