Calculates the tangent of an angle.

Syntax

Tan(Angle)

The syntax of the Tan function consists of the following parts:

Remarks

The result has the same structure as the argument Angle. The calculation is done element by element where appropriate.

The result has the unit 1, if Angle has a unit. Otherwise, it has no unit.

The real tangent function is calculated for a real argument. The result is always of the 64-bit floating point value data type. The following illustration shows the course of the function:

If Angle is complex, then the complex tangent function is calculated, which can be defined as follows:

i * (Exp(-i * Angle) - Exp(i * Angle)) / (Exp(-i * Angle) + Exp(i * Angle)) with the imaginary unit i = (0, 1).

The result is always of the complex 64-bit floating point value data type. The following illustration shows the course of the absolute value of the function:

If the argument is a list, then the function is executed for each element of the list and the result is also a list.
