TAN(nExpression)

Return Values

Numeric

Parameters

• nExpression
  Specifies the angle in radians for which TAN( ) returns the tangent. To convert an angle from degrees to radians, use DTOR( ). The number of decimal places returned by TAN( ) can be specified with SET DECIMALS.

Example

CLEAR
? TAN(0)  && Displays 0.00
? TAN(PI( )/4)  && Displays 1.00
? TAN(PI( )*3/4)  && Displays -1.00
