Description

Returns sine and cosine of an angle.

Call SinCos to obtain the sine and cosine of an angle expressed in radians. Theta specifies the angle. The sine and cosine are returned in the Sin and Cos parameters, respectively.

SinCos is twice as fast as calling Sin and Cos separately for the same angle.
