Definition: | atom x2 = sin(atom x1) |
Description: | Return the sine of x1, where x1 is in radians. |
Comments: | This function may be applied to an atom or sq_sin() to all elements of a sequence.
The rules for
sequence operations apply.
Note that the following diagram uses degrees, ie sin(30*CD_DEG2RAD) = 0.5, where CD_DEG2RAD is defined in pGUI as PI/180. ![]() |
Example: |
sin_x = sin(.9) -- sin_x is 0.783 |
