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.

SEE ALSO

     cacos(3), ccosh(3), complex(3), cos(3), math(3), sin(3), tan(3)

STANDARDS

     These functions conform to ISO/IEC 9899:1999 (``ISO C99'').

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).

STANDARDS

     The csin(), ccos(), and ctan() functions conform to ISO/IEC 9899:2011.
