NAME
ccos, ccosf, ccosl - complex cosine functionSYNOPSIS
#include <complex.h>
double complex ccos(double complex z);
float complex ccosf(float complex z);
long double complex ccosl(long double complex z);
Link with -lm.
DESCRIPTION
These functions calculate the complex cosine of z.The complex cosine function is defined as:
ccos(z) = (exp(i * z) + exp(-i * z)) / 2
VERSIONS
These functions first appeared in glibc in version 2.1.ATTRIBUTES
