ccos(3) Library Functions Manual ccos(3)
ccos, ccosf, ccosl - complex cosine function
Math library (libm, -lm)
#include <complex.h> double complex ccos(double complex z); float complex ccosf(float complex z); long double complex ccosl(long double complex z);
These functions calculate the complex cosine of z. The complex cosine function is defined as: ccos(z) = (exp(i * z) + exp(-i * z)) / 2
