Alternate Sine Implementation Missing

[Adam Stambler]

Hi All,

On the wiki page for trig functions,  there is a description of an alternate sine function where they use the symmetry of the sine and the following function to just operate in -pi/2 to pi/2. 

if (angle > (pi / 2))
    angle = pi - angle;
else if (angle < -(pi / 2))
    angle = -pi - angle;

However, when I look through the code for sin, it is not present in the library.  Am I missing something?

Regards,

Adam
