Sin (FPScript)

21.09.2021

Calculates the sine of an angle.

Syntax

Sin(Angle)

 

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

Part

Description

Angle

The angle in radians.

All data structures are allowed. All numeric data types are permitted.

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 sine function is calculated for a real argument. The result is 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 sine function is calculated, which can be defined as follows:

(Exp(i * Angle) - Exp(-i * Angle)) / (2 * i) with the imaginary unit i = (0, 1).

The result is then 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.
