TAN
The tangent of an angle in radians.
Group: Math. Compatible with DAX.
Syntax
TAN ( <number> )| Parameter | Type | Description |
|---|---|---|
number | Number | An angle in radians. |
Returns
Number. The tangent of the angle: its sine divided by its cosine.
Remarks
- Angles are in radians. To work in degrees, wrap the angle in
RADIANSfirst. - A blank gives BLANK.
- Near a right angle (pi / 2) the tangent grows without bound; the computer gives a very large number there, not an error.
- Very large angles, such as 1E9 radians, are an error.
