ccos(3) Library Functions Manual ccos(3) NAME ccos, ccosf, ccosl - complex cosine function LIBRARY Math library (libm, -lm) SYNOPSIS #include <complex.h> double complex ccos(double complex z); float complex ccosf(float complex z); long double complex ccosl(long double complex z); 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 were added in glibc 2.1.
