ccosh(3) Library Functions Manual ccosh(3)
ccosh, ccoshf, ccoshl - complex hyperbolic cosine
Math library (libm, -lm)
#include <complex.h>
double complex ccosh(double complex z);
float complex ccoshf(float complex z);
long double complex ccoshl(long double complex z);
These functions calculate the complex hyperbolic cosine of z.
The complex hyperbolic cosine function is defined as:
ccosh(z) = (exp(z)+exp(-z))/2
C11, POSIX.1-2008.
glibc 2.1. C99, POSIX.1-2001.
