Sin (FPScript)
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.
