NAME

ccosh, ccoshf, ccoshl — complex hyperbolic cosine

SYNOPSIS

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);

DESCRIPTION

The ccosh(), ccoshf() and ccoshl() functions compute the complex hyperbolic cosine of z.

If z = x + iy, then

ccosh(z) = cosh(x) cos(y) + i sinh(x) sin(y).

RETURN VALUES

The ccosh(), ccoshf() and ccoshl() functions return the complex hyperbolic cosine of z.

SEE ALSO

csinh(3), ctanh(3)

STANDARDS

The ccosh(), ccoshf() and ccoshl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
