The TAN trigonometric function returns the tangent of an angle expressed in radians.
This function can be useful to measure the rate of change between consecutive periods in a rolling trend analysis.
Syntax
TAN(Angle)
Arguments
| Argument | Data type | Description |
| Angle | Number | The angle in radians for which you want to calculate the tangent. Use the |
The TAN() function returns a numeric value. But, it becomes undefined at odd multiples of π/2, such as ±π/2, ±3π/2, and others, where the function approaches infinity.
Calculation engine functionality differences
This function is only available in the Polaris Calculation Engine.
Syntax example
TAN(PI() / 4)
Additional information
Returns NaN when Angle is NaN.
