sincos, sincosf, sincosl - calculate sin and cos simultaneously
void sincos(double x, double *sin, double *cos);
void sincosf(float x, float *sin, float *cos);
void sincosl(long double x, long double *sin, long double *cos);
Link with -lm.
Several applications need sine and cosine of the same angle x. This
function computes both at the same time, and stores the results via the
This function is a GNU extension.
