TAN

Syntax

TAN (Data)

Description

The TAN function returns the tangent of Data, where Data represents an angle in radians.

To convert from degrees to radians, multiply by PI( ) / 180. (The PI function returns the value of PI.)

Returns

Returns the tangent of Data, where Data represents an angle in radians.

Example

These examples employ the TAN built-in function:

• TAN(PI( )) returns 0 (tangent of p radians).

• TAN(PI( ) / 4) returns 1 (tangent of p / 4 radians).

• TAN(45 * PI( ) / 180) returns 1 (tangent of 45 degrees).
