sincos
(), sincosf
(), and
sincosl
() functions compute the sine and cosine of
x. Using these functions allows argument reduction to
occur only once instead of twice with individual invocations of
sin
() and cos
(). Like
sin
() and cos
(), a large
magnitude argument may yield a result with little or no significance.
sincos
(),
sincosf
(), and sincosl
(), the
memory pointed to by *s and *c are
assigned the values of sine and cosine, respectively.
