NAME

ccos, ccosf, csin, csinf, ctan, ctanf — complex trigonometric functions

LIBRARY

Math Library (libm, -lm)

SYNOPSIS

#include <complex.h>

double complex
ccos(double complex z);

float complex
ccosf(float complex z);

double complex
csin(double complex z);

float complex
csinf(float complex z);

double complex
ctan(double complex z);

float complex
ctanf(float complex z);

DESCRIPTION

The ccos(), csin(), and ctan() functions compute the cosine, sine, and tangent of the complex number z, respectively. The ccosf(), csinf(), and ctanf() functions perform the same operations in float precision.
