Purpose |
Return the tangent of its argument. |
|
Syntax |
y = TAN(numeric_expression) |
|
Remarks |
numeric_expression is an angle specified in radians. To convert radians to degrees, multiply by 57.29577951308232##. To convert degrees to radians, multiply by 0.0174532925199433##. For more information on radians, see ATN. TAN returns an Extended-precision result. TAN is approximated with the expression: TAN = SIN(Value) / COS(Value) The Inverse Tangent (ARCTAN) of a value can be easily calculated with the ATN function. The Hyperbolic Tangent (TANH) of a value can be calculated: TanH = (EXP(2 * Value) - 1) / (EXP(2 * Value) + 1) The Inverse Hyperbolic Tangent (ARCTANH) of a value can be calculated: ArcTanH = LOG((1 + Value) / (1 - Value)) / 2
