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. SEE ALSO

CSIN(3) BSD Library Functions Manual CSIN(3) NAME
csin -- complex sine function ccos -- complex cosine function ctan -- complex tangent function SYNOPSIS
#include <complex.h> double complex csin(double complex z); long double complex csinl(long double complex z); float complex csinf(float complex z); double complex ccos(double complex z); long double complex ccosl(long double complex z); float complex ccosf(float complex z); double complex ctan(double complex z); long double complex ctanl(long double complex z); float complex ctanf(float complex z); DESCRIPTION
csin(z) computes the sine of the complex floating-point number z. ccos(z) computes the cosine of the complex floating-point number z. ctan(z) computes the tangent of the complex floating-point number z. NOTES
csin, ccos, and ctan are defined in terms of the complex hyperbolic functions as follows: csin(z) = -i * csinh(i*z), ccos(z) = ccosh(i*z), ctan(z) = -i * ctanh(i*z). SEE ALSO
