-===== Sin (Function) =====
-==== Format ====
-**sin** ( [[numericexpressions|numeric_expression]] )
-returns [[floatexpressions|float_expression]]
-==== Description ====
-Computes the sine of [[expressions|expression]]. //Expression// must be in radians.
-==== Note ====
-The sin function does not produce an exact result.
-==== Example ====
-<code>
-clg
-color black
-# draw a line across the graphic output
-line 0,150,300,150
-# where do we start
-lastx = 0
-lasty = sin(0) * 50 + 150
-# now step across the line and draw
-for x = 0 to 300 step 5
-   angle = x / 300 * 2 * pi
-   y = sin(angle) * 50 + 150
-   line lastx, lasty, x, y
-   lastx = x
-   lasty = y
-next x
-</code>
