TAN( ) function

Returns the tangent of an angle expressed in radians, with a precision of 15 decimal places.

Syntax

TAN(radians)

Parameters

Name	Type	Description
radians	numeric	The measurement of the angle in radians.

Output

Numeric.

Examples

Basic examples

Returns 0.999999999999999 (the tangent of the specified number of radians, equivalent to 45 degrees):

TAN(0.785398163397448)

Returns 0.999999999999999 (the tangent of 45 degrees):

TAN(45 * PI( )/180)

Advanced examples

Using degrees as input

Returns 1.000 (the tangent of 45 degrees, rounded to 3 decimal places):

DEC(TAN(45 * PI( )/180),3)

Remarks

Performing the Mantissa Arc Test

The three trigonometric functions in Analytics – SIN( ), COS( ), and TAN( ) – support performing the Mantissa Arc Test associated with Benford's Law.

Converting degrees to radians

If your input is in degrees you can use the PI( ) function to convert the input to radians: (degrees * PI( )/180) = radians. If required, you can round or truncate the return value using the DEC( ) function.
